    We Are Not Alone In The Universe
    I cannot imagine any single discovery that would have more impact on humanity than the discovery of life outside of our solar system. There is a human-centric, Earth-centric view of life that permeates most cultural and societal thinking. Finding that there are multiple, perhaps millions of origins of life and that life is ubiquitous throughout the universe will profoundly affect every human.

    We live on a microbial planet. There are one million microbial cells per cubic centimeter of water in our oceans, lakes, and rivers; deep within the Earth's crust and throughout our atmosphere. We have more than 100 trillion microbes on and in each of us. The Earth's diversity of life would have seemed like science fiction to our ancestors. We have microbes that can withstand millions of Rads of ionizing radiation; such strong acid or base that it would dissolve our skin; microbes that grow in ice and microbes that grow and thrive at temperatures exceeding 100 degrees C. We have a life that lives on carbon dioxide, on methane, on sulfur, or on sugar. We have sent trillions of bacteria into space over the last few billion years and we have exchanged material with Mars on a constant basis, so it would be very surprised if we do not find evidence of microbial life in our solar system, particularly on Mars.

    The recent discoveries by Dimitar Sasselov and colleagues of numerous Earth and super-Earth-like planets outside our solar system, including water worlds, greatly increases the probability of finding life. Sasselov estimates approximately 100,000 Earth and super-Earths within our own galaxy. The universe is young so wherever we find microbial life there will be intelligent life in the future.

    Expanding our scientific reach further into the skies will change us forever.

  • PLANET JUST LIKE EARTH: Alien Life - National Geographic Documentary HD

    50:42

    When NASA began 60 years ago, we had questions about the universe humans had been asking since we first looked up into the night sky. In the six decades since, NASA, along with its international partners and thousands of researchers, have expanded our knowledge of the Universe by using a full fleet of telescopes and satellites. From the early probes of the 1950s and 1960s to the great telescopes of the 1990s and 21st century, NASA scientists have been exploring the evolution of the universe from the Big Bang to the present.

    The Great Observatories
    NASA astronomers use several kinds of telescopes in space and on the ground. Each observes targets like stars, planets, and galaxies, but captures different wavelengths of light using various techniques to add to our understanding of these cosmic phenomenon.
    Dark Matter
    NASA telescopes have helped us better understand this mysterious, invisible matter that is five times the mass of regular matter. The first direct detection of dark matter was made in 2007 through observations of the Bullet Cluster of galaxies by the Chandra x-ray telescope.

    Black Holes
    Although we can’t “see” black holes, scientists have been able to study them by observing how they interact with the environment around them with telescopes like Swift, Chandra, and Hubble. In 2017, NASA's Swift telescope has mapped the death spiral of a star as it is consumed by a black hole. This year, astronomers using Chandra have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy.
    Galaxies
    A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, held together by gravity. Some are spiral-shaped like our Milky Way Galaxy; others are smooth and oval shaped. NASA telescopes are helping us learn about how galaxies formed and evolved over time.
    Exoplanets
    Just 30 years ago, scientists didn’t know if there were planets orbiting other stars besides our own Sun. Now, scientists believe every star likely has at least one exoplanet. They come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze. They can orbit their stars so tightly that a “year” lasts only a few days; they can even orbit two stars at once. Some exoplanets don’t orbit around a star, but wander through the galaxy in permanent darkness. NASA’s Kepler spacecraft and newly-launched Transiting Exoplanet Survey Satellite are helping us find more distant worlds

  • ANOTHER EARTH | KEPLER 186F - Full Documentary

    54:12

    If Alien exist where do they live and how do they live?
    Scientists say a world that's 490 light-years away qualifies as the first confirmed Earth-sized exoplanet that could sustain life as we know it — but in an environment like nothing we've ever seen.
    The planet, known as Kepler-186f, is more of an Earth cousin than an Earth twin, Elisa Quintana, an astronomer at the SETI Institute at NASA Ames Research Center, told the journal Science. Quintana is the lead author of a report on the planet published by Science this week.
    This discovery does confirm that Earth-sized planets do exist in the habitable zones of other stars, Quintana said during a Thursday news briefing at NASA Headquarters.
    Kepler-186f goes around an M-type dwarf star that's smaller and cooler than our sun. But it orbits much closer to its parent star than Earth does, within what would be Mercury's orbit in our own solar system. Those two factors combine to produce an environment that could allow for liquid water on the surface, assuming that the planet had a heat-trapping atmosphere.

    The star, to our eyes, would look slightly orange-y, about a third again as big as our sun but only a third as bright, said co-author Thomas Barclay, a staff scientist for NASA's Kepler mission who is also affiliated with NASA and the Bay Area Environmental Research Institute. At midday, Kepler-186f's landscape might look similar to what we see on Earth an hour before sunset, he told NBC News.
    Or it might not: If the planet lacked an atmosphere to retain and redistribute its sun's warmth, it would be a cold, dry, lifeless world.

    Kepler-186f probably rates as the most potentially Earthlike planet discovered so far, said Jim Kasting, a geoscientist at Penn State University who did not play a role in the Science study. But he told NBC News that it's still less likely to be habitable than planets around more sunlike stars. Even better prospects for alien habitability might well be identified in the months and years to come.

    How the world was found

    Kepler-186f is just the latest discovery to be pulled out of terabytes' worth of data collected by the Kepler mission. Before it went on the fritz last year, the Kepler space telescope stared at more than 150,000 stars in a patch of sky, looking for the telltale dimming of starlight as planets passed over the stars' disks. Nearly 1,000 exoplanets have been confirmed using Kepler data, and almost 3,000 more candidates are still awaiting confirmation.

    It takes years of observation to confirm the pattern of dimming and brightening that's associated with alien planets, particularly if the planets are small and far from their parent stars. In February, astronomers reported that at least four worlds circled the dwarf star known as Kepler-186 or KOI-571. In this week's Science paper, Quintana and her colleagues confirm the existence of Kepler-186f as the fifth and outermost world.
    They report that Kepler-186f is about 10 percent wider than Earth, tracing a 130-day orbit around its sun at a mean distance of 0.35 astronomical units. (An astronomical unit is the distance between Earth and our sun, which is 93 million miles or 150 million kilometers.) That would put Kepler-186f on the cooler, outer side of the star's habitable zone — the range of orbital distances where liquid water could exist on a planet's surface.

    Astronomers have confirmed the existence of other planets in their stars' habitable zone, but those prospects are super-Earth-size. Smaller habitable-zone candidates also have been found, but they have yet to be confirmed as planets.

    Barclay said Kepler-186f was particularly promising because it's less than 1.5 times the size of Earth. Planets in that size range are more likely to be rocky with a thinner atmosphere, like Earth, Mars and Venus. But worlds exceeding that size stand a better chance of retaining a thick atmosphere of hydrogen and helium, like the giant planet Neptune.

    While those planets also could be rocky, they don't remind us of home, Barclay said.
    Could we actually detect signs of life on Kepler-186f? That's a tough one. The astronomers behind the discovery acknowledge that the planet might be just too far away for follow-up studies. The SETI Institute has been searching for radio signals from the Kepler-186 system over a wide frequency range (1 to 10 GHz), but so far nothing has been detected.

  • The Earth is Not Alone | Alien Planet

    2:46:41

    People began traveling in space in 1961 in tiny spacecraft called capsules, which were launched from Earth by powerful rockets. Russian crews still travel in this kind of craft, in Soyuz capsules, but Americans now travel into space in shuttles, which are rocket-powered space planes.

    HOW DO HUMANS SURVIVE IN SPACE?
    There is no oxygen in space, so all crewed spacecraft carry a life-support system. This supplies air for people to breathe. The system also includes equipment to keep the air at a comfortable temperature and pressure and to remove carbon dioxide and odors.

    HOW DOES SPACE TRAVEL AFFECT PEOPLE?
    Gravity in space is much weaker than it is on Earth. When people travel in space, they seem to become weightless. This often makes them feel sick. Their bodies do not have to work as hard, because they are not fighting gravity to sit or stand up. If they stay in space for a long time, the lack of gravity makes their muscles start to waste away. Exercise and a special diet help to combat these effects.

    WHAT IS THE FARTHEST ANYONE HAS TRAVELED IN SPACE?
    Astronauts on the APOLLO PROJECT traveled to the Moon, about 239,000 miles (385,000 km) away. Russian cosmonaut Valeri Poliakov traveled a distance of about 174 million miles (280 million km) around Earth while in the Mir space station.

    APOLLO PROJECT
    In the space race of the 1960s, the US Apollo Project beat the Soviet Union by landing the first astronauts on the Moon. The first Moon landing, by Apollo 11, took place on July 20, 1969, when Neil Armstrong and Buzz Aldrin became the first humans to set foot on another world.

    WHAT WAS THE APOLLO SPACECRAFT LIKE?
    The Apollo spacecraft was launched from Earth by the Saturn V rocket. On the launch pad, the whole assembly stood 365 ft (111 m) tall. The spacecraft itself weighed 50 tons (45 metric tons). It was made from three main modules (sections). The command module for flight control housed the three-person crew. The service module carried equipment, fuel, and a rocket motor. The lunar module detached from the craft and landed two astronauts on the Moon’s surface.

    HOW MANY APOLLO LANDINGS WERE THERE?
    There were six Moon landings, beginning with Apollo 11 in July 1969 and ending with Apollo 17 in December 1972. During the missions, 12 astronauts explored the lunar surface for a total of over 80 hours and brought back nearly 880 lb (400 kg) of Moon rock and dust for examination on Earth.

  • Alien Planet

    1:34:01

    The CGI or computer animated drama/documentary takes place on Darwin IV, a planet 6.5 light years from earth, with 2 suns and 60% of Earth's gravity. Having identified Darwin as a world that could support life, Earth sends a pilot mission consisting of the Mothership Von Braun and three probes: Balboa, Da Vinci, and Newton. This robotic fleet is responsible for finding and assessing any life forms on Darwin IV. Initially, the expectation is to find microscopic life, but the probes soon find themselves in the middle of a developed ecosystem teeming with diversity of life of all sizes. The drama on Darwin IV is motivated by real science missions, such as the NASA Origins Program and the NASA / JPL Planet-Finder Mission, as well as the European Space Agency's Darwin Project. Alien Planet is a cosmic expedition along side Stephen Hawking, Michio Kaku, Jack Horner, Craig Venter, and George Lucas...

  • The Search For A Second Earth - Space Documentary HD

    3:37:23

    In the 400 years since Galileo Galilei first held a telescope to the heavens, astronomers have laid bare some of the deepest mysteries of the cosmos. They have seen comets crash into planets, found oceans inside moons, and witnessed the shudder of spacetime as black holes collide.

    But space remains a realm of the unknown. Writing in the journal Nature on Thursday, scientists in Canada reported the detection of mysterious radio signals from halfway across the universe. It is only the second time that repeating fast radio bursts, or FRBs, have been spotted.

    Astronomers have yet to formulate a full theory of what produces these enigmatic, rapid-fire beams of electromagnetic waves. And in the absence of a firm explanation, speculation has fallen, perhaps inevitably, on alien civilisations. Avi Loeb, a Harvard astronomer, has proposed that FRBs might be powerful energy beams used to propel alien spacecraft.

    It is not the first time that poorly-understood cosmic phenomena have been ascribed to industrious extraterrestrials. When in 2015 astronomers noticed a star, 1,500 light years distant, dimming and brightening, researchers suggested an “alien megastructure” might be revolving around it, and collecting energy for its constructors. Then, in 2017, the massive cigar-shaped ‘Oumuamua barrelled into the solar system, the first interstellar object known to do so, and prompted speculation that it was a tumbling spacecraft.

    Chris French, head of the Anomalistic Psychology Research Unit at Goldsmiths, University of London, said it was natural for humans to see aliens behind every cosmic mystery. “We have what is called an intentionality bias,” he said. “It’s the assumption that whenever something happens, something or someone made it happen for a reason. In the context of space, that someone is always going to be aliens.”

    The evolutionary argument for intentionality bias, or “agenticity”, is that our ancient ancestors fared better if a rustle in the bushes made them run for cover rather than assume it was the wind. “At the end of the day, our brains evolved to keep us alive rather than apprehend the truth of the universe,” said French.

    The late astronomer Carl Sagan spotted the dilemma for scientists. They can become cranks if they are too open-minded, but may miss out on landmark discoveries if they are not open-minded enough. “It seems to me what is called for is an exquisite balance between two conflicting needs,” he said. “The most sceptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas.”

    Duncan Lorimer, an astrophysicist at West Virginia University, discovered the first FRB in 2007. When his team spotted the radio burst, the possibility of it being a message from ET certainly came up. “We absolutely thought about aliens,” he said. “We only had the one object. We looked for patterns in the signal and couldn’t find anything, but we definitely considered it.”

    Now, mention of aliens is beginning to wear thin. “It helps to sell the story, but at this point I do roll my eyes a bit,” he said. Many astronomers now favour the idea that FRBs are intense beams of radiation shed by charged particles as they are whipped around by strongly magnetised neutron stars. “It seems like a more plausible idea, but I don’t want to rule out aliens completely,” he said. “I’ve been wrong before.”

  • Saturns Moon Titan: Another Earth? - Documentary HD

    54:23

    Alien life, Saturn's Moon Titan: Another Earth?
    Saturn’s largest moon Titan is an extraordinary and exceptional world. Among our solar system’s more than 150 known moons, Titan is the only one with a substantial atmosphere. And of all the places in the solar system, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes, and seas on its surface.
    Titan is larger than the planet Mercury and is the second-largest moon in our solar system. Jupiter's moon Ganymede is just a little bit larger (by about 2 percent). Titan’s atmosphere is made mostly of nitrogen, like Earth’s, but with a surface pressure 50 percent higher than Earth’s. Titan has clouds, rain, rivers, lakes and seas of liquid hydrocarbons like methane and ethane. The largest seas are hundreds of feet deep and hundreds of miles wide. Beneath Titan’s thick crust of water, ice is more liquid—an ocean primarily of water rather than methane. Titan’s subsurface water could be a place to harbor life as we know it, while it's surface lakes and seas of liquid hydrocarbons could conceivably harbor life that uses different chemistry than we’re used to—that is, life as we don’t yet know it. Titan could also be a lifeless world.
    Did You Know?
    As exotic as Titan might sound, in some ways it’s one of the most hospitable worlds in the solar system. Titan’s nitrogen atmosphere is so dense that a human wouldn’t need a pressure suit to walk around on the surface. He or she would, however, need an oxygen mask and protection against the cold—temperatures at Titan’s surface are around minus 290 degrees Fahrenheit (minus 179 Celsius).

    Titan’s dense atmosphere, as well as gravity roughly equivalent to Earth’s Moon, mean that a raindrop falling through Titan’s sky would fall more slowly than on Earth. While Earth rain falls at about 20 miles per hour (9.2 meters per second), scientists have calculated that rain on Titan falls at about 3.5 miles per hour (1.6 meters per second), or about six times more slowly than Earth’s rain. Titan’s raindrops can also be pretty large. The maximum diameter of Earth raindrops is about 0.25 inches (6.5 millimeters) while raindrops on Titan can reach diameters of 0.37 inches (9.5 millimeters), or about 50 percent larger than an Earth raindrop.
    Pop Culture
    Titan was famously featured in the 2009 film “Star Trek”—the U.S.S. Enterprise comes out of warp in Titan’s atmosphere in order to sneak up on the Romulan ship attacking Earth. Titan also appeared in the film “Star Trek Nemesis,” as well as an episode of “Star Trek: The Next Generation.” Several other television shows and films feature Titan, such as the film “Gattaca,” and the shows “Futurama” and “Eureka,” as well as the iconic anime series “Cowboy Bebop.” Dozens of video games also feature Titan, as do several comics from Marvel and DC, among others.

    Titan has been a setting or subject in dozens of short stories and novels by giants of science fiction including Arthur C. Clarke, Philip K. Dick, and Isaac Asimov, as well as legendary “Star Trek” actress Nichelle Nichols. Even literary greats such as Kurt Vonnegut have included Titan in their fiction.

  • UFOS & ALIENS - The Myth Of Space Travel | SPACETIME - SCIENCE SHOW

    48:51

    For more than 40 years, people have lived in space over longer periods of time - first on the space stations Saljut and Skylab, today on the international space station ISS, and perhaps soon in a spaceship on its way to Mars. But man is not made for space. The universe is so hostile to life that humans can not survive there permanently. Skeptics, conspiracy theorists claim that all manned space travel is just a well-staged drama and the moon landing is the biggest lie of all. Since man has set out to conquer outer space and then the universe, conspiracy theorists accompany the work of scientists and explorers. And at the same time, UFOs (unidentified flying objects) have been sighted with claims of visits by your favorite martian aka extraterrestrials. Mankind’s advance into space has triggered the imagination of earthlings since humans first looked up at the stars. And so, in addition to the epochal discoveries, countless myths and legends have arisen as well.

    The world is not enough for conspiracy theories. Since the first launches into space numerous myths and legends around space travel and astronauts abounded. The first images from space depicted our planet in spherical form. All lies was a cry heard immediately from so-called experts.: The earth is and remains a disc. To this day, there are advocates of the flat earth theory, which was actually refuted even before the birth of Christ.

    The claim that the earth is flat was almost extinct, but the Internet is helping fuel this theory in a kind of renaissance of fools. Any kind of conspiracy theory ever invented in the context of space travel is getting a revival in the age of the world wide web. The biggest of all is the denial of the successful landing of man on the moon.

    Hardly any other human event spawned such wild speculation as Neil Armstrong's moon landing as well as the eleven other US astronauts. Just a few months after the first steps on the Moon, skeptics accused NASA, its scientists and astronauts, and the entire US government as liars. The landing never took place, the live images were recorded in Hollywood studios, the whole moon program is a huge bluff. To this day, despite proof to the contrary, the conspiracy theorists continue to beat the drum of denial.
    But there is also a lot happening on planet Earth. Ever since man conquered space, first with balloons and then with airplanes, earth dwellers regularly sight unknown flying objects: UFOs. The first UFOs were reported at the end of the 19th century; at about the same time as the first attempts to launch aircraft heavier than air into the sky. The UFOs levitate alien creatures on Earth to collect humans as research objects or to keep in contact with the powerful leaders of the world. There’s more: US military are thought to have captured several extraterrestrials and keep them hidden in a secret facility, including the flying saucers they landed with. The site: A US Air Force test site in the Nevada desert known as Area 51.
    But even everyday problems and phenomena of manned and unmanned space travel repeatedly create fodder for skeptics, doubters and conspiracy theorists. Sci Fi movies are also fantastic sources for creating new myths and legends.
    In this Episode of Spacetime we try to shed some light on the dark realm of conspiracies, myths and legends. Astronaut Ulrich Walter explains what really happens to people in space, should they find themselves without a spacesuit. He shows us how to live and survive in weightlessness and why even flights deep into the solar system do not have to be lethal to humans. We look at what UFO sightings are all about and what's behind them and why Area 51 is so mysterious.
    We examine the surface of Mars, which appeared on the first photos of the Red Planet and terrified crowds of people. We explain the function of the warp drive and whether you can really travel through the universe with it. And of course we explain why man actually set foot on the moon.

  • Alien Planets Like Earth 2014 Documentary

    51:47

    Are there Extraterrestrial planets like 'Earth' exist in space?
    Habitable alien planets similar to Earth may not be that rare in the universe, a new study suggests.
    About one in five sunlike stars observed by NASA's planet-hunting Kepler spacecraft has an Earth-size planet in the so-called habitable zone, where liquid water - and, potentially life - could exist, according to the new study. If these results apply elsewhere in the galaxy, the nearest such planet could be just 12 light-years away.

    Human beings have been looking at the stars for thousands of years, said study researcher Erik Petigura, a graduate student at the University of California, Berkeley (UC Berkeley). How many of those stars have planets that are in some way like Earth?

    AD28
    In Today's Episode, I'm Going To Tell You...
    NASA found a new planet like earth in Hindi | Kepler 1649C Full Information Explained
    Scientists discovered this planet, called Kepler-1649c when looking through old observations from Kepler, which the agency retired in 2018. While previous searches with a computer algorithm misidentified it, researchers reviewing Kepler data took a second look at the signature and recognized it as a planet. Out of all the exoplanets found by Kepler, this distant world – located 300 light-years from Earth – is most similar to Earth in size and estimated temperature.

  • Which Planet Will Humanity Live On Next? | Planet Hunters | Spark

    41:32

    The first extra-solar planet – or exoplanet – was only discovered in 1995. Now, a new space-based telescope has discovered thousands more, and some of them may be just like Earth.
    Planet Hunters follows the astrophysicists at the forefront of the search for Earth’s twin, and tells the little-known story of the two Canadians who invented the technique that made modern planet-hunting possible. Gordon Walker and Bruce Campbell also detected the first exoplanet ever discovered, but that’s not what the history books say…

    Secrets Of Earth : Hindi Documentary

    Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.[n 5]

    Earth's axis of rotation is tilted, producing seasonal variations on the planet's surface. The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest of the four terrestrial planets.

    Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans.[29] The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.

    Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive. In the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species[32] that ever lived on Earth are extinct.[33][34] Estimates of the number of species on Earth today vary widely;[35][36][37] most species have not been described.[38] Over 7.4 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans have developed diverse societies and cultures; politically, the world has about 200 sovereign states.

  • A Potentially Habitable Super Earth Has Been Discovered

    10:02

    The universe is too big for us to be the only ones in it. It's just a matter of knowing where to look, and scientists from NASA's TESS program might have stumbled across the next clue in this galactic scavenger hunt. The Transiting Exoplanet Survey Satellite was launched in April of 2019 with the aim of locating planets in orbit around nearby stars.

    One of these stars is the comparatively small GEE-JAY 357. It's about 31 light-years from Earth. It's one of the closest to Earth! Thanks to TESS, NASA astronomers discovered a planet orbiting this distant star. And in fact, it’s one of the few whose atmosphere can be studied by scientists, once they determine if it has one!

    Can we expect any alien visitors? 5:03
    Why we can't see those planets directly 6:57

    #planets #space #brightside

    SUMMARY:
    - GEE-JAY 357 b is believed to be about twenty-two percent larger than Earth, and eleven times closer to its star than Mercury is to the Sun.
    - Scientists have discovered planets beyond our solar system before, but GEE-JAY 357-b is one of the closest to Earth.
    - Hidden beyond the semi-molten glow of this “hot Earth,” as astronomers called it, were two more planets. One of them, GEE-JAY 357-d is just far enough from the star to potentially support life.
    - Its orbiting inside its solar system's habitable zone, warm enough to support life, but not so warm that it ends up charbroiled.
    - NASA scientists estimate that that planet has an average temperature of about minus sixty-four degrees. That’s cold, comparable to the interior of Antarctica.
    - I wouldn’t expect any alien visitors for most of the same reasons humans will probably never be visiting GEE-JAY 357-d for themselves.
    - If intelligent life developed, there’s no reason to believe it wouldn’t sooner or later turn its sensory organs to the stars. That's when the planet's gravity becomes an obstacle. I
    - Scientists have estimated that reaching the moon of a planet ten times the size of Earth, would require almost five hundred thousand tons of fuel to get off the ground.
    - It is worth noting that Astronomers haven't yet been able to see any of these planets directly. The TESS only discovered the massive and hot planet b because of its silhouette passing in front of the star.
    - Since c and d never passed between Earth and GEE-JAY 357 during the month when TESS was able to capture images of the star, we've only been able to study them indirectly.
    - The middle planet, called GEE-JAY 357-c just to make things confusing, didn’t even give us that. Because of its unusually tilted orbit, this planet never passes between Earth and its star at all.

  • ANOTHER EARTH: Alien Planet - 2020 Space Documentary HD

    2:36:57

    We Are Not Alone In The Universe
    I cannot imagine any single discovery that would have more impact on humanity than the discovery of life outside of our solar system. There is a human-centric, Earth-centric view of life that permeates most cultural and societal thinking. Finding that there are multiple, perhaps millions of origins of life and that life is ubiquitous throughout the universe will profoundly affect every human.

    We live on a microbial planet. There are one million microbial cells per cubic centimeter of water in our oceans, lakes and rivers; deep within the Earth's crust and throughout our atmosphere. We have more than 100 trillion microbes on and in each of us. The Earth's diversity of life would have seemed like science fiction to our ancestors. We have microbes that can withstand millions of Rads of ionizing radiation; such strong acid or base that it would dissolve our skin; microbes that grow in ice and microbes that grow and thrive at temperatures exceeding 100 degrees C. We have life that lives on carbon dioxide, on methane, on sulfur, or on sugar. We have sent trillions of bacteria into space over the last few billion years and we have exchanged material with Mars on a constant basis, so it would be very surprising if we do not find evidence of microbial life in our solar system, particularly on Mars.

    The recent discoveries by Dimitar Sasselov and colleagues of numerous Earth and super-Earth-like planets outside our solar system, including water worlds, greatly increases the probability of finding life. Sasselov estimates approximately 100,000 Earth and super-Earths within our own galaxy. The universe is young so wherever we find microbial life there will be intelligent life in the future.

    Expanding our scientific reach further into the skies will change us forever.

  • Pluto and its Moons - Space Documentary 2019 HD

    52:58

    In 2006, the International Astronomical Union, a global group of astronomy experts, established a definition of a planet that required it to clear its orbit, or in other words, be the largest gravitational force in its orbit.

    Since Neptune's gravity influences its neighboring planet Pluto, and Pluto shares its orbit with frozen gases and objects in the Kuiper belt, that meant Pluto was out of planet status. However, in a new study published online Wednesday in the journal Icarus, UCF planetary scientist Philip Metzger, who is with the university's Florida Space Institute, reported that this standard for classifying planets is not supported in the research literature.

    Metzger, who is lead author on the study, reviewed scientific literature from the past 200 years and found only one publication -- from 1802 -- that used the clearing-orbit requirement to classify planets, and it was based on since-disproven reasoning.

    He said moons such as Saturn's Titan and Jupiter's Europa have been routinely called planets by planetary scientists since the time of Galileo.

    The IAU definition would say that the fundamental object of planetary science, the planet, is supposed to be a defined on the basis of a concept that nobody uses in their research, Metzger said. And it would leave out the second-most complex, interesting planet in our solar system. We now have a list of well over 100 recent examples of planetary scientists using the word planet in a way that violates the IAU definition, but they are doing it because it's functionally useful, he said. It's a sloppy definition, Metzger said of the IAU's definition. They didn't say what they meant by clearing their orbit. If you take that literally, then there are no planets, because no planet clears its orbit.

    The planetary scientist said that the literature review showed that the real division between planets and other celestial bodies, such as asteroids, occurred in the early 1950s when Gerard Kuiper published a paper that made the distinction based on how they were formed.

    However, even this reason is no longer considered a factor that determines if a celestial body is a planet, Metzger said.

    Study co-author Kirby Runyon, with Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said the IAU's definition was erroneous since the literature review showed that clearing orbit is not a standard that is used for distinguishing asteroids from planets, as the IAU claimed when crafting the 2006 definition of planets.

    We showed that this is a false historical claim, Runyon said. It is therefore fallacious to apply the same reasoning to Pluto, he said. Metzger said that the definition of a planet should be based on its intrinsic properties, rather than ones that can change, such as the dynamics of a planet's orbit. Dynamics are not constant, they are constantly changing, Metzger said. So, they are not the fundamental description of a body, they are just the occupation of a body at a current era.

    Instead, Metzger recommends classifying a planet based on if it is large enough that its gravity allows it to become spherical in shape.

    And that's not just an arbitrary definition, Metzger said. It turns out this is an important milestone in the evolution of a planetary body, because apparently when it happens, it initiates active geology in the body.

    Pluto, for instance, has an underground ocean, a multilayer atmosphere, organic compounds, evidence of ancient lakes and multiple moons, he said.

    It's more dynamic and alive than Mars, Metzger said. The only planet that has more complex geology is the Earth.

    Get the latest from the planet-hunting frontier. Find out what we are learning about our place in the cosmos from the search for earth-like planets.

    This journey started tens of thousands of years ago, when humans began to fan out across the planet, following unknown pathways, crossing unmeasured distances. We traced coastlines, and sailed uncertain seas. We crossed ocean straits drained by an ice age.

    Into every corner of Earth we ventured, looking for places to put down our roots, to raise our families, or just to see what was there. Today, it's the final frontier that fires our imaginations. With so many stars in our galaxy, we make a simple extrapolation, that the cosmos must be filled with worlds like ours, with life, even intelligent life.

    For four years, the historic planet hunting mission, Kepler, starred at a group of 150,000 stars located in a region extending three thousand light years away from earth.

    The data collected by this spacecraft has brought a turning point in the long search for other planets like earth. Is ours one of countless life-bearing worlds strewn about the galaxy; or is it a rare garden of eden in a barren universe?

  • Better than Earth: Superhabitable Exoplanets with Prof. Abel Mendez

    1:7:03

    Where is the best place in the universe to look for life?
    With the discovery of water in the atmosphere of the exoplanet k218b we are closing to answering if is there life on other planets? As well, is there life in our solar system? Could there be life on the moons of Jupiter, Europa and Enceladus.Or have we already found life in meteorites like the Allan hills 84001? And with the discovery of interstellar objects like oumuamua and comet 2I/Borisov, do they carry life through panspermia through the interstellar medium?

    Professor Abel Mendez is a planetary astrobiologist and Director of the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. His research focuses on the habitability of Earth, the Solar System, and extrasolar planets. Prof. Méndez is a NASA MIRS Fellow with physics and astrophysics research experience at Fermilab, NASA Goddard, NASA Ames, and the Arecibo Observatory.

    With the estimated sheer size of the universe, it's very likely that a planet with near-identical features to our own could exist somewhere. In the last two decades, we have discovered a huge number of Earth-like planets within merely a few thousand light years of us, let alone within the entire expanse of the universe. As such, humanity has been looking to find the first planet worthy of acting as the second natural human colony. The challenge thereafter will be developing the technology to reach such an Earth-like planet, more commonly referred to as an Earth Analog.

A couple of weeks ago what I now understand to be a hard drive malfunction caused my laptop to completely die, with no way to recover it. I still may be able to recover some files in the future, but until that time I simply had to start again with my entire video portfolio - and this is my first project. I have been away from YouTube for some time now and have finally got my motivation back, given how long I had to wait. So expect some more videos, and some shorter ones, coming in the next few weeks. I've been quite sick recently, but I'm on the mend now and I hope to get back to my best soon. Thanks for those who stuck by and waited, you're all awesome- and I hope this was enough to act as the first part of an apology!

    An alien planet thought to be made largely of diamond may be less than glittering inside. The notion of a diamond planet hinges on an abundance of carbon.

  • Earth vs Outer Space - Documentary

    Earth vs Outer Space - New Documentary
    Outer space, or just space, is the void that exists between celestial bodies, including the Earth. It is not completely empty, but consists of a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust and cosmic rays. The baseline temperature, as set by the background radiation from the Big Bang, is 2.7 kelvins (K) (−270.45 °C; −454.81 °F). Plasma with a number density of less than one hydrogen atom per cubic metre and a temperature of millions of kelvins in the space between galaxies accounts for most of the baryonic (ordinary) matter in outer space; local concentrations have condensed into stars and galaxies. In most galaxies, observations provide evidence that 90% of the mass is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Data indicates that the majority of the mass-energy in the observable universe is a poorly understood vacuum energy of space which astronomers label dark energy. Intergalactic space takes up most of the volume of the Universe, but even galaxies and star systems consist almost entirely of empty space...

  • Is There Intelligent Life On Other Planets?

    How are we looking and listening for intelligent life?

    ↓↓↓ More info and sources below ↓↓↓

    Now that we know planets are common in our galaxy, how would we tell if one holds life? Sure, it will take incredibly powerful telescopes and ambitious new space missions, but what are we looking for? What are we listening for? How do we help other worlds know that we are here?

    Here's the thing: Life on Earth has an expiration date. No matter what humans do, our aging sun will eventually be so hot that we can't survive. If we want to live on, it will have to be beyond Earth. The only question is, will it be US who live on, or just our radio broadcasts and dead satellites?
