    ----------------------------------------------------------------------------------
    Astrophysicist Neil deGrasse Tyson joins us to talk about one of our favorite subjects: space.

    In the three-chaptered video, Tyson speaks about the search for alien life inside and outside of the Goldilocks Zone, why the term dark matter should really be called dark gravity, and how the rotation of the Earth may have been the deciding factor in a football game.

    These fascinating space facts, as well as others shared in Tyson's books, make it easier for everyone to grasp complex ideas that are literally out of this world.
    ----------------------------------------------------------------------------------
    NEIL DEGRASSE TYSON:

    Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. He is the first occupant of the Frederick P. Rose Directorship of the Hayden Planetarium. His professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way. Tyson obtains his data from the Hubble Space Telescope, as well as from telescopes in California, New Mexico, Arizona, and in the Andes Mountains of Chile.Tyson is the recipient of nine honorary doctorates and the NASA Distinguished Public Service Medal. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid 13123 Tyson.

    Tyson's new book is Astrophysics for People in a Hurry, you can check it at

    TRANSCRIPT:

    NEIL DEGRASSE TYSON: When we think of places you might find life we typically think of the Goldilocks Zone around the star where water would be liquid in its natural state. And if you get a little too close to the star, heat would evaporate the water and you don't have it anymore. It's gone. Too far away it would freeze and neither of those states of H2O are useful to life as we know it. We need liquid water. So you can establish this Green Zone, this habitable zone, this Goldilocks Zone, where if you find a planet orbiting there hey, good chance it could have liquid water. Let's look there first for life as we know it.

    Now it turns out that this source of heat, of course is traceable to the sun and if you go farther out everything water should be frozen, all other things being equal. But Europa, a moon of Jupiter sitting well outside of the Goldilocks Zone is kept warm not from energy sources traceable to the Sun, but from what we call the tidal forces of Jupiter itself. So, Jupiter and surrounding moons are actually pumping energy into Europa. And how does it do that? As Europa orbits Jupiter its shape changes. It's not fundamentally different from tides rising and falling on Earth. The shape of the water system of the Earth is responding to tidal forces of the moon. And when you do that to a solid object, the solid object is stressing. And because of this, a consequence of this is that you are pumping energy into the object. It is no different from when you say to anyone who's familiar with racquet sports, indoor racquet sports. It could be racquetball or squash. You say let's arm up the ball before we start playing.

    You want to hit it around a few times. You are literally warming up the ball. It's not just simply let's get loose. You are literally warming up the ball. How? You are distorting it every time you smack it and then the resilience of the ball pops it back into shape and every time you do that, every smack, you're pumping energy into the ball. It's not fundamentally different from what's going on in orbit around Jupiter. So, you have this frozen world, Europa, completely frozen on its surface but you look at the surface and there are cracks in the ice. There are ridges in the ice where there's a crack and it shifted and then refroze. So this ridge has a discontinuity in the crack and it continues in another place. So what this tells you is that Europe cannot be completely frozen because if it were nothing would be moving. You look at the surface of Europa, the frozen surface, there are like ice chunks that are shifted and refrozen and shifted again. It looks just like if you fly over the Arctic Ocean.

    Fly over the Arctic Ocean in the winter...

  • Neil deGrasse Tyson - The Most Astounding Fact

    3:36

    The most astounding fact is the knowledge that the atoms that comprise life on Earth the atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas cloud that condense, collapse, form the next generation of solar systems stars with orbiting planets, and those planets now have the ingredients for life itself.

    So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the Universe is in us.

    When I reflect on that fact, I look up -- many people feel small because they're small and the Universe is big -- but I feel big, because my atoms came from those stars.

    There's a level of connectivity.

    That's really what you want in life, you want to feel connected, you want to feel relevant you want to feel like a participant in the goings on of activities and events around you That's precisely what we are, just by being alive...

  • Neil deGrasse Tyson Explains Space

    9:29

    What is space? In this explainer, Neil deGrasse Tyson and Chuck Nice explore the boundaries of space...the definition that is.

    We talk about space a lot, but what is it? You’ll learn about different levels of orbit, where we draw the line of where earth ends and space begins, and how far the International Space Station is from the surface of the earth. Is the ISS always in space? Should our definition of space be based on our planet’s atmosphere? Should we change our definition? How many astronauts have actually been to space? All that and more on another StarTalk explainer!

    Note: This live show was filmed prior to the COVID 19 pandemic. All content recorded since then has been up to safety standards with social distancing, mask mandates, and vaccination in mind. We look forward to doing our part to make sure that we can make events like this one happen safely again soon.

    How good is food in space? On this episode, Neil deGrasse Tyson and comic co-host Jordan Klepper feast on food science and the challenges we face sending food to space with chef Alton Brown, food chemist Dr. Arielle Johnson and NASA food scientist Dr. Grace Douglas.

    Can you become a better cook through science? Find out about the creative field of flavor science and what molecular gastronomy is. How can we still make good food with constraints? Discover how one of the top restaurants in the world, Noma, uses ants to replace lemons. What is retro-nasal olfaction? What happens when we taste something? Can you invent a new smell or flavor that’s never been experienced before? Can we take our palates to the limit?

    We explore the Advanced Food Technology project at NASA: How do you create food for space? You’ll learn how they find the perfect balance between safety, nutrition, and flavor for the astronauts. Can they just grow space potatoes like in The Martian? Do astronauts lose their sense of taste? Is there a food space race? How important is variety in their food? What is the feedback like from the astronauts? How many options do they get for dinner? If we had to choose one food to live on, what would we choose? We discuss the ritualism around food preparation, closed loop systems, and how food helps us feel at home. How close are we to growing our own food in space? Is the future of space exploration vegetarian?

    Where is food science heading in the face of climate change? Can fixes to Mars’ problems have applications for us on Earth? Do we need to diversify our palates? We break down the impact of climate change on growing patterns, food availability, and bees. Could we have bees in the ISS? Are there chemical solutions to these problems? We try to answer the question: How do we do the same thing with fewer resources? All of that, plus, find out about NASA initiatives to solve these problems and what the future of space food looks like.

  • Neil deGrasse Tyson Explains Nothing

    13:45

    In this StarTalk video, we’re talking about nothing. Not in the Seinfeldian sense, but in the science sense. What is nothing? Neil explains how our usual definition of something being “nothing” is dictated by our senses.

    What if you wanted to get all the way down to true nothing? Well, even when there’s nothing, there’s air molecules, and a lot of them. So, what happens when you take out the air molecules? Find out just how much air molecules permeate in our environment, in our solar system, in interstellar space, and intergalactic space.

    Then, just when you think you truly have nothing, you’ll hear how quantum physics comes into play. Discover more about virtual particles and why the best “nothing” you could have is filled with virtual particles. All that, plus, we debate if being able to describe something that is nothing makes it something.

  • The Origin of The Universe With Neil deGrasse Tyson

    10:02

    The origin of the universe is certainly among the most intriguing topics in all of science. Neil deGrasse Tyson explains how the universe came to be. He explains the big bang theory and the subsequent evolution of the universe.

    Neil deGrasse Tyson not only explains the origin of the Universe, he also gives an inspiring speech about the origin of life on Earth and our place in the cosmos.

    The universe has inspired scientific discoveries in a broad array of disciplines including astronomy, physics, chemistry, mathematics, and biology. The Big Bang itself forms the basis of the current Standard Model of cosmology, which describes the evolution of the universe from the earliest known states through the appearance of structural fragments.

    The latest data shows that the expansion of the universe is accelerating. This means that the galaxies are moving further apart from each other which indicates that space is stretching. It has been suggested to explain this by the gravitational potential of dark energy. This theory suggests that dark energy has a positive pressure which pushes the universe apart.

    Dark energy is the most accepted explanation for the observations of an accelerating universe. And it remains an active field of research in cosmology.

    Neil deGrasse Tyson also briefly mentions the Multiverse hypothesis and how it fits with the big bang model.

    Information from modern experiments, such as the Planck satellite and WMAP short for Wilkinson Microwave Anisotropy Probe, and from astronomical observations in the 21st century, has allowed cosmologists to increase the precision of their predictions about the universe's age early in the universe's history.

    It is fascinating to think how much of the nature of the universe science has revealed to us. But we're still only scratching the surface of a cosmic iceberg. Most of the universe, and the multiverse, if it exists, still remains in the realm of the unknown. But scientists are determined in the quest to expand the frontier of knowledge and push the boundaries of ignorance, and shed a light to an ever growing and expanding universe.

  • Neil deGrasse Tyson: Are We Alone in The Universe?

    10:13

    Neil deGrasse Tyson explains the possibility of life existing elsewhere in the Universe. He explains where the elements that make up life on Earth come from. And how that has profound implications about the prevalence of life in the Universe. Certainly the question Are we alone in the Universe has got to be among the oldest, most fascinating and awe inspiring questions in science that remains unanswered. But Neil deGrasse Tyson paints a very interesting cosmic picture about life itself and why most astrophysicists indeed accept the probability of the existence of extraterrestrial life is high. At the very end he also has what he calls a disturbing and thought provoking question for the viewers.

    So far, the only life we know of is right here on our planet Earth. Yet, there are compelling arguments to suggest we are not alone.
    There are thousands of exoplanets that have been confirmed to exist in our galaxy and the likely number could be in the trillions.

    Given how long life has had to evolve on Earth, it is possible that there are beings on other worlds that are even more advanced than we are. That would certainly have implications for our understanding of the origins of life.

    A new study however, suggests that alien civilizations destroy themselves through progress, meaning our galaxy could be full of dead alien civilizations.

    With a limited understanding of how life originated on Earth, and with so little understanding of what kind of life there is elsewhere in the universe, it is not too surprising we don’t know what we are going to find out there. But it seems very likely that other life will have developed in different ways to that which evolved on Earth.

    So, are we alone in the universe? As Arthur C. Clarke has pointed out “Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying.

  • StarTalk Podcast: Cosmic Queries – Edge of the Universe with Neil deGrasse Tyson and Janna Levin

    53:26

    What’s beyond the edge of the universe? Is there even an edge at all? On this episode of StarTalk Radio, Neil deGrasse Tyson answers your fan-submitted questions about the mysteries, wonders, and theories that exist on the bleeding edge of cosmology. But in order to explore the true depths of the unknown we need to bring in a little extra help – enter astrophysicist Janna Levin, PhD.

    We start with the basics: is the universe infinite? Janna tells us why we’re still uncertain. We explore the idea of the multiverse and the idea of our universe never having an “edge.” Could those distant galaxies we see be our own galaxy in the past? As if that’s not mind-bending enough, we haven’t even gotten to the dimensionality questions yet.

    Find out more about other possible dimensions. We discuss why it’s so difficult to detect other dimensions, if they’re even there in the first place. Janna and Neil help us visualize a 4th dimension. You’ll hear why adding another dimension might provide too much freedom for molecules to bind together and create macroscopic things. We also explore the idea that our three dimensions are glued to a membrane that’s floating in a higher dimensional space. We reflect on Monsters, Inc. and how the film plays with moving through different dimensions.

    Discover more about the shape of our universe. Could it be in the shape of a loop? We break down the Big Bang and the birth of the universe. Find out more about dark matter, dark energy, and if they’re two sides of the same coin. Janna explains why dark energy should be thought of as an invisible ocean. Investigate the “information” that lies on the surface of a black hole. We track Voyager 2’s journey into interstellar space and what that means for us back on Earth. All that, plus, Janna shares why she thinks the study of dark matter and dark energy are the most important fields of study in science today.

    Michio Kaku: 3 mind-blowing predictions about the future

    ----------------------------------------------------------------------------------
    Carl Sagan believed humanity needed to become a multi-planet species as an insurance policy against the next huge catastrophe on Earth. Now, Elon Musk is working to see that mission through, starting with a colony of a million humans on Mars. Where will our species go next?

    Theoretical physicist Michio Kaku looks decades into the future and makes three bold predictions about human space travel, the potential of 'brain net', and our coming victory over cancer.

    [I]n the future, the word 'tumor' will disappear from the English language, says Kaku. We will have years of warning that there is a colony of cancer cells growing in our body. And our descendants will wonder: How could we fear cancer so much?
    ----------------------------------------------------------------------------------
    MICHIO KAKU:

    Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).

    Read Michio Kaku's latest book The Future of Humanity: Our Destiny in the Universe at
    ----------------------------------------------------------------------------------
    TRANSCRIPT:

    MICHIO KAKU: We are entering what I call the next golden era of space exploration. We have not just new energy and new financing and money coming from Silicon Valley, we also have a new vision emerging. For Elon Musk of SpaceX it's to create a multi-planet species. However, for Jeff Bezos of Amazon, he wants to make Earth into a park so that all the heavy industries, all the pollution, goes into outer space. And Jeff Bezos wants to set an Amazon-type delivery system connecting the earth to the moon. And so he wants to lift all the heavy industries off the planet Earth to make Earth a paradise and to put all the heavy industries in outer space.

    Now, I once talked to Carl Sagan and he said that because the earth is in the middle of a shooting gallery of asteroids and comets and meteors, it's inevitable that we will be hit with a planet buster. Something like what hit the dinosaurs, 65 million years ago, we need an insurance policy. Now, he was clear to say that we're not talking about moving the population of the earth into outer space—that costs too much money. And we have problems of our own on the earth like global warming. We have to deal with those problems on the earth not flee to outer space. But as an insurance policy, we have to make sure that humans become a two-planet species. These are the words of Carl Sagan.

    And now, of course, Elon Musk has revived this vision by talking about a multi-planet species. He wants to put up to a million colonists on the planet Mars, sent to Mars by his rockets financed by a combination of public and private funding, including fusion rockets, ramjet fusion rockets, including anti-matter rockets. Some of these rockets, of course, their technologies won't be available till the next 100 years. However, the laws of physics make it possible to send postage-stamp-size chips to the nearby stars. So think of a chip, perhaps this big, on a parachute and have thousands of them sent into outer space energized by perhaps 800 megawatts of laser power. By shooting this gigantic bank of laser energy into outer space, by energizing all these mini-parachutes you could then begin to accelerate them to about 20% the speed of light. This is with doable technology today. It's just a question of engineering. It's a question of political will and economics but there's no physics, there's no law of physics preventing you from shooting these chips to 20% the speed of light. That means Proxima Centauri, part of the Alpha Centauri triple star system, could be within the range of such a device. Now think about that. That means that within 20 years, after 20 years of launch, we might be able to have the first starship go to a nearby planet. And it turns out that Proxima Centauri B is an Earth-like planet that circles around the closest star to the planet Earth—what a coincidence. So it means that we've already staked out our first destination for visitation by an interstellar starship. And that...

  • 60+ Mind-Blowing Space Facts That Might Scare You And Amaze at the Same Time

    21:49

    We think we know everything about the place we live in: we might know our neighbors, the owner of the closest supermarket, the guy who always walks his dog in the nearest park. How about the bigger place we live in - our planet Earth, or even bigger - our Galaxy? Do you know what's going on right above our heads, in outer Space?

    Some of the object in Space constantly bump into each other, like meteors and planets, or comets and stars, or even two black holes. Black holes collisions are so powerful that they send gravitational waves all across cosmos. Some of the fine-tuned detectors here on Earth even allow us to hear the sound from those collisions. I wonder, what it sounds like!

  • Neil deGrasse Tyson Explains The Weirdness of Quantum Physics

    10:24

    Quantum mechanics is the area of physics that deals with the behaviour of atoms and particles on microscopic scales. Since its inception, the many counter-intuitive aspects and results of quantum mechanics have provoked strong philosophical debates and many interpretations.

    Neil deGrasse Tyson explains quantum physics in a way that is understandable even for the lay person. In Quantum Mechanics there is no such thing as absolute certainty when looking for something. This phenomenon is known as Uncertainty Principle and was Introduced first in 1927 by the German physicist Werner Heisenberg. Heisenberg realized that one implication of quantum physics is that the act of measurement always disturbs the object measured.

    Neil deGrasse Tyson explains that the whole computer world is based on the principle of Quantum Physics. We are able to manipulate the electrical properties of silicon only because we can study the wave nature of electrons.

    Our daily routines are often governed by technology that is directly related to Quantum Physics, thus our lives rest upon these fundamental scientific discoveries.

    Another hard concept to grasp is Quantum entanglement. Einstein referred to it as spooky action at a distance. It occurs when a pair or group of particles is generated, interact, or share spatial proximity in a way such that the quantum state of each particle of the pair or group cannot be described independently of the state of the others. But Neil deGrasse Tyson and Lawrence Krauss explain this concept with everyday life examples which makes it a little bit easier to understand.

    As Neil deGrasse Tyson points out, the first quantum phenomena were observed more than a century ago. However scientists are still learning about this realm of our universe.

  • The Fermi Paradox With Neil deGrasse Tyson - Where Are All The Aliens?

    12:12

    Since the birth of philosophy, we've never stopped wondering about the answer to the question: Are we alone?
    Neil deGrasse Tyson tackles the possibility of the prevalence of life in the cosmos by comparing our sole data-point we have, life on Earth. He points to the fact that life on Earth formed as soon as it had a chance after the late heavy bombardment period.

    Neil deGrasse Tyson also extrapolates from the fossil record that Intelligence as we humans have defined it is not necessary for survival, therefore intelligent life in the cosmos might be extremely rare.

    In the summer of 1950 Italian-American physicist Enrico Fermi, while walking to lunch with his fellow physicists was having a casual conversation about recent UFO reports and the possibility of faster-than-light travel. Allegedly Fermi suddenly during lunch said, But where is everybody?

    This later became known as the Fermi problem or paradox. Which is the apparent contradiction between the lack of evidence for extraterrestrial life and the high estimate probability for their existence.

    So what could possibly explain this semblant paradox?

    Whatever is preventing non-living matter from undergoing Abiogenesis in time, to expanding lasting life as measured by the Kardashev scale, in the context of the Fermi paradox, is known as the Great Filter.

    As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address our endless curiosity for the possibility of life existing elsewhere in the cosmos. Within our solar system, NASA’s missions have searched for signs of both ancient and current life, especially on Mars and soon, Jupiter’s moon Europa. Beyond our solar system, missions, such as Kepler, are revealing thousands of planets orbiting other stars. Fueling our imaginations further with bewilderment, wondering if there are other civilizations out there, perhaps asking the same question. Are we alone?

    A growing number of people believe we've already answered this question due to recent UFO reports over the last few years. However, eye-witness testimony and ambiguous video footage does not qualify as extraordinary evidence to definitively answer this age old question. But to be respectful to the people who believe we've been visited by extraterrestrial crafts, we will dedicate a whole video on the topic.

  • Neil deGrasse Tyson Explains How Quantum Physics Can Spoil Food

    14:45

    How can quantum physics spoil food? You know how food usually spoils, but quantum physics?! On this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice are here to fill you in on the physics of what’s going on in your fridge.

    First, we need to know how most food commonly spoils. Neil tells us about the “normal” way food goes bad which involves microbes, bacteria, and temperature. We explore unpasteurized milk vs. pasteurized milk.

    Then, Neil explains how quantum physics can spoil your food (after a really long time). We discuss “quantum tunneling.” You’ll learn about the behavior of molecules and their continual quest to be “happy.” All that, plus, find out if there’s anything you can do to stop this quantum phenomena.

  • Telescopes, Liquid Mercury, and The Death of Black Holes - Cosmic Queries

    47:21

    Terraforming mars? How do black holes die? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer questions about the moon, periodic table of elements, light photons, black holes and more!

    Find out about the moon’s libration and orbit. How much of our moon do we actually see? We observe patterns from Neil’s time in front of the camera. What film franchise will he wreak havoc on next? Back to the non-human stars: have modern humans always lived under the same night sky? Will there be a day when we no longer recognize the constellations?

    Why is mercury– the element, not the planet– liquid? Why does one proton make such a big difference? Discover the states of the elements on other worlds and the meaning of a “triple point.” Is it possible to terraform Mars, even though it doesn’t have a magnetic field? We explore geoengineering and how to terraform to protect against solar wind.

    Next, we talk telescopes. How much does the moon disrupt observation time? How do we combat that? We discuss the James Webb Space Telescope, Hubble Deep Field, and how astronomers combat interference. How does a light photon experience time? Does it? Can a black hole’s mass get so low it can no longer trap light? What would it look like? How does a black hole die? All that, plus, Chuck tests out new joke material on another Cosmic Queries!

  • The Multiverse Hypothesis Explained by Neil deGrasse Tyson

    10:03

    The multiverse hypothesis or theory holds that a group of multiple universes (possibly infinite universes) comprise everything that exists: The entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The renowned astrophysicist Neil deGrasse Tyson explains in detail the multiverse hypothesis.

    However, prominent physicists are divided about whether any other universes exist outside of our own. Some even go as far as to say that the multiverse is not a legitimate topic of scientific inquiry. Because it can not be empirically falsified. But Neil deGrasse Tyson among other prominent cosmologists, thinks that given our understanding of quantum mechanics and the theory of General relativity, the possibility of the existence of the multiverse is a legitimate scientific hypothesis.

    Steven Weinberg said that if the multiverse existed, the hope of finding a rational explanation for the precise values of quark masses and other constants of the standard model that we observe in our Big Bang is doomed, for their values would be an accident of the particular part of the multiverse in which we live.

    Some scientists analyzed the data from the Wilkinson Microwave Anisotropy Probe, an uncrewed spacecraft operating from 2001 to 2010 that measured temperature differences across the sky in the cosmic microwave background, the radiant heat remaining from the Big Bang, and claimed they found evidence suggesting that our universe collided with other parallel universes in the distant past.

    However, a more thorough data analysis from the Wilkinson Microwave Anisotropy Probe and from the Planck Satellite, a space observatory operated by the European Space Agency from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background, did not find any statistically significant evidence of universe collisions. there was no evidence of any gravitational pull of other universes on ours either. And to add insult to injury to the proponents that the multiverse hypothesis has been backed up by statistical evidence, the Planck satellite, has a resolution three times higher than the WMA Probe.


    Our brains are not evolutionarily equipped to intuitively understand quantum mechanics and large scale cosmic phenomena. But Neil deGrasse Tyson with his usual wits explains the multiverse hypothesis in layman's terms.

  • StarTalk Podcast: COVID-19 and Mental Health, with Neil deGrasse Tyson

    49:12

    On this episode of StarTalk Radio, we’re continuing our series of episodes covering the current COVID-19 pandemic. On this edition, Neil deGrasse Tyson is joined by comic co-host Chuck Nice and neuroscientist Heather Berlin, PhD to explore the relationship between the pandemic and mental health.

    How has the human condition adapted to the pandemic? Heather tells us why a certain subset of people previously suffering from OCD have gotten better. We investigate the rise in social anxiety and whether that will stay present after the situation has improved. We also examine why people are pushing against safety regulations and the quarantine. We compare the way a collective society works opposed to an individualistic society.

    Then, it’s time to dive into fan-submitted Cosmic Queries. Find out of there are positive effects on mental health during this state. Neil tells us about Isaac Newton’s isolation from a plague that resulted in important discoveries in gravity. Heather discusses the increased role of mental health professionals. But that begs the question from Neil, how much training can a mental health professional have to prepare for a pandemic?

    You’ll learn more about the importance of sunlight during times of quarantine, especially for those living where their homes might not receive a lot of daily light. Heather explains how your pre-existing personality shapes how you respond to the current environmental circumstances. We ponder if there will be a rise in agoraphobia once society fully opens up.

    In our last segment, StarTalk Sports Edition co-host Gary O’Reilly joins our trio to discuss how athletes are dealing with being in quarantine. How can athletes retain their super-fast mental processing speeds while not competing? And, as sporting leagues start to play again, how will players react to playing in front of empty stadiums? We ponder whether sports might be less aggressive or competitive without fans present to watch in person. All that, plus, we debate how long sports has to be sidelined in order for people to lose interest.

    18:46

    1,000,000,000,000,000,000,000. That’s the estimated number of stars in the universe. That’s a pretty big number. But, how did we get here? And, can we go bigger? You bet we can go bigger. In this video, Neil deGrasse Tyson and comic co-host Chuck Nice are here to help you understand how big some numbers truly are.

    We have to start small. Neil takes us from a simple million to a billion and then way beyond anything you’re imagining. You’ll learn how many stars are in our galaxy. And, how many galaxies are in our universe. What does the number really mean in the scale of everything?

    How long would it take you to count to a billion? How long would it take you to count to a trillion? Then, we cross the point where numbers get so big that you have to start using words to describe them. Discover more about a mole, a googol, a googolplex, and Skewes’ number. After this video, you’ll look at numbers a whole different way!

  • Neil deGrasse Tyson and NASA Chief Scientist Explain New Mars Rover

    18:43

    Earlier in the day today, @NASA successfully launched their latest Mars rover, Perseverance. Now that it’s rocketing its way to Mars, we’re here to explore what it will do once it gets there. Neil deGrasse Tyson and comic co-host Chuck Nice are joined by NASA Chief Scientist James Green, PhD, to break down what Perseverance will be doing once it touches down on the red surface.

    Firstly, why launch now? James tells us why this is the perfect window to launch to Mars. You’ll learn why NASA is targeting to land Perseverance on an ancient Martian shoreline. We discuss why our own evolution history helps inform us where to land the rover.

    Find out the logistics of how Perseverance will land on the Martian surface. Will we experience a similar six minutes of terror like we experienced when Curiosity made its descent? James explains why the landing procedures may sound crazy but they actually make “fantastic sense.”

    You’ll hear about all the different experiments attached to Perseverance including a rock corer, high-tech cameras, and a ground-penetrating radar. Lastly, James tells us about Ingenuity, the tiny helicopter accompanying Perseverance on this mission. All that, plus, find out why James is excited to have a microphone on-board Perseverance.

    What is the North Star? Where is it in the night sky? Are stars in Hollywood burning thermonuclear fuel in their core? We discuss how culturally entrenched wishing on a star is, why the North Star– Polaris– has significance, and why so many people can’t seem to spot it. We break down long exposure photos of the night sky and the constellations in the southern hemisphere. Is there a “south star”? Plus, hear Chuck’s impersonation of Venus getting mistaken for Polaris and more!
