The Beginning and Evolution of the Universe - How to Search for Exoplanets Documentary

  • The Search for Life in the Universe Documentary - The Science of Exoplanets Discovery


    How do we find other planets?
    For life in the universe to be abundant, planets must be abundant. But planets are hard to detect because they are small, and much fainter than the stars they orbit.

    How does life begin?
    Scientists do not yet know how the first living things arose on Earth. The geological record shows that life appeared on Earth almost as soon as the young planet was cool and stable enough for living things to survive. This suggests that life may exist wherever conditions allow it.

  • The Search for Life in the Universe Documentary - Discovery and Exploration of the Planets


    We ask the world's leading space scientists what we might find if we travel to a neighboring star system. Recent breakthroughs have proven that every star we see in the sky is orbited by at least one planet, many similar to our own Earth. How do we get to these exoplanets? Once there, what will we find? And what will it mean for humanity when we discover we are not alone?

  • THE UNIVERSE - Out of Nothing: Infinity | SPACETIME - SCIENCE SHOW


    SPACETIME - SCIENCE SHOW: The beginning of everything was the Big Bang. The creation of our universe was set in motion. But what came before the big bang? And what happened right after the big bang? We are fascinated by the infinite vastness of the universe. A vastness inconceivable to anything we can imagine. But how do we know that the universe is infinite? These are the questions humanity has been preoccupied with since we looked up at the stars: where do we come from? Where are we going? And where is our place in the infinity of the cosmos?

    The Big Bang is the absolute starting point of our universe. The birth of space and time. But was there really nothing before that? A nothing beyond our imagination, or was there something before the big bang? What cosmologists and astrophysicists can say with certainty: Our universe came into existence exactly 13.8 billion years ago. And everything started from a single speck. A tiny speck where our three-dimensional universe, space, was buried. But where was this speck, this dot? There is no answer comprehensible for average human imagination. Only mathematics helps here. And it states: this three-dimensional, strongly curved speck was just there.

    After the big bang, our universe ballooned. And continues to expand today, maybe for all eternity. Nevertheless, astronomers define the universe as manageable: it is as big as the eye can see. It consists of what we can observe in principle. In order to discover and observe galaxies and stars, we need to light. The light of our central star, our sun, takes 8 minutes to reach us. The light of the nearest stars a few years. Tens of thousands of years from the next galaxies. The Hubble Space Telescope photographs galaxies several billion light-years away, and satellites measure the microwave radiation produced only 400,000 years after the Big Bang. With this data, cosmologists measure our universe in space and time.

    Let there be light! In this episode of Spacetime, Professor Ulrich Walter explains how out of nowhere our universe emerged. How it expanded, and what happened and continues to happen today. We focus on the question whether our Universe will last forever, or whether it is finite. What would happen at the end? We examine the phenomena that our cosmos holds: What are dark energy and dark matter? Why black holes exist and how do wormholes work? Are there really parallel universes? And what does the detection of gravitational waves mean for science? We look at the theories, methods and instruments that cosmologists use to track down the origin and function of our universe.
    The view into space gives us images of a fascinating and bewildering beauty. Landscapes of light and gas and stardust, shaped by cosmic wind and radiation. We are surrounded by an intangible infinity. A universe in which the earth is just a grain of sand on the beach of an ocean. But we are deciphering more and more secrets of the universe around us.

  • History of the Planets in Solar System Documentary The Universe


    To the Greeks and Romans there were seven known planets, each presumed to be circling Earth according to the complex laws laid out by Ptolemy. They were, in increasing order from Earth (in Ptolemy's order and using modern names): the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn

  • Does the Universe Have an Edge Documentary - Universe Expanding Faster Than We Though


    The Milky Way is the galaxy we live in, one of the countless collections of stars and dust throughout the universe. It's a reality so basic, grade school kids learn it.

    Just 100 years ago, the nature of the Milky Way — and the universe itself — was still a matter of debate. On April 26, 1920, astronomer Harlow Shapley claimed our galaxy was the entire universe. Astronomer Heber Curtis countered that the blurry star clusters seen with a telescope were “island universes,” separate from, but analogous to, the Milky Way.

    Within five years, Edwin Hubble produced a reliable distance to one of the clusters we now know is our neighbor, the Andromeda Galaxy. His measurements showed that the gulf is so vast, Andromeda must be outside the Milky Way. Upon seeing a note from Hubble describing the results, Shapley said, “Here is the letter that destroyed my universe.” He wasn’t all wrong, though. In the years since, his prediction that our solar system is far from the Milky Way’s center was proven true.

  • Living Universe | Journey To Another Stars - Documentary 4K


    The Earth is Not Alone:
    LIVING UNIVERSE is an interstellar adventure that seeks to answer the most profound question of all: are we alone? Based on the latest scientific knowledge, we will take a journey to a planet beyond our solar system in search of life.

    We ask the world's leading space scientists what we might find if we travel to a neighboring star system. Recent breakthroughs have proven that every star we see in the sky is orbited by at least one planet, many similar to our own Earth. How do we get to these exoplanets? Once there, what will we find? And what will it mean for humanity when we discover we are not alone?

    Our speculative journey through space is set a hundred years in the future - when we have the technology to journey well beyond our solar system. On this first expedition, our star ship Aurora will be piloted not by astronauts, but by the artificial intelligence (A.I.) we call Artemis. We imagine how Artemis travels through space, on its 25-year journey, at one fifth of the speed of light. Its objective is Minerva B, a planet much like our own, with an atmosphere, temperature and liquid water that appears a likely candidate to contain life.

    With spectacular special effects we will reach and explore a new planet as we seek to answer the most profound question of all: are we alone in the universe? Our guides on this journey are narrator Dr Karl Kruszelnicki and as the voice of our AI, Artemis, real-life astrophysicist, Professor Tamara Davis.

    Inspired and informed by our rapidly developing knowledge of far-off worlds, our best scientists - including NASA engineers, astrophysicists and astronomers - we will discover that this amazing journey is not only possible, it is inevitable. To venture into distant space is our destiny.

    LIVING UNIVERSE captures a pivotal moment in the human story. A film full of insight and inspiration certain to thrill anyone who dreams of distant worlds, or have ever wondered why are we here?

    Have you ever wondered that someone like you, sitting less than a mile away, in some other universe, exists? The possibility in itself seems frightening as well as astonishing.

    From breaking news and intriguing historical documentaries to conspiracy theories, classified NASA files and UFO's. We provide you with material that the government doesn't want you to see. The Insomnia team comes up with a promise. To keep up with the same, the team now brings to us a documentary that aims to change your perspective Of another existence, of another possibility, as today, the scientists now believe there may really be the presence of a parallel universe - and in fact, also believe that there may be an infinite number of parallel universes, and where we live today just happens to be only one of them and many of these other parallel universes come with different laws of physics as well.

    These other universes that we are talking about not only contain space, time and strange forms of exotic matter but to surprise you, Some of them may even contain you, only maybe in a slightly different form. The thought itself is quite intriguing and scary on the same hand. The basis of this theory is as we know it the idea that parallel universes are constantly spinning off from reality that we humans know of. Though generally ignored at the time, that theory has gone on to become not just a popular topic of study among respected physicists, but the inspiration for such popular films, television shows, and books as Star Trek and The Golden Compass. according to the sources.

    The video soon progresses into the Wilkinson Microwave Anisotropy Probe (WMAP), that is now changing everything, as some say that the remarkable images reveal the true shape of the universe through baby pictures of the same from the time when it was 4 hundred thousand years old, looking so back in time, when there wasn't even the formation of galaxies yet. The WMAP is catching the very first signs of creation as it is officially tagged with measuring radiation that is left over from Big Bang. And now scientists have devised an experiment to find the overall true shape of the universe. The WMAP hence shows that the universe is flat. From here arises the possibility of more mind boggling parallel universe that are of the level-2 type and is made up of giant cosmic soap bubbles that float in hyperspace. Each of these bubbles within it has a whole universe. Now, the question that arises is that - Do we all live in a giant cosmic bubble?

  • Exploring and Understanding our Universe Documentary - Searching for Alien Life on other Planets


    Earth-like planets may not be so special after all, and that's good news for scientists involved in the search for alien life.

    A new analysis of light from nearby stars suggests that rocky worlds like our own are plentiful in our Milky Way galaxy. In turn, the finding suggests that many exoplanets — possibly with magnetic fields, substantial atmospheres and tectonic plates that bring minerals to the surface — could have conditions that allowed life to evolve there.

    “When we started to find planets around other stars, the odds of life existing on other stars went up,” said Edward Young, a geochemist at the University of California, Los Angeles, and a co-author of a paper about the new research published Oct. 18 in the journal Science. “When we started finding rocky planets, they went up again — and now we are finding evidence that the rocky planets could be similar to Earth, so now the odds have gone up yet again.”

  • Exoplanets: The Search for New Worlds


    A few decades ago, we knew of no other planets beyond those in our solar system. Today, astronomers have confirmed over 700 planets circling other suns and believe billions more lay undiscovered. These new worlds have smashed conventional assumptions, revealing planets orbiting multiple stars, planets that don’t orbit stars at all, and at least one as airy as Styrofoam. The incredible boom in planetary diversity raises tantalizing prospects for an Earth analog that could harbor life—as we know it, and as we never imagined it.

    This program is part of The Big Idea Series, made possible with support from the John Templeton Foundation.

    The Real Star Trek discovers the challenges humankind will have to overcome to journey to distant stars.

    One day we may face no choice but to leave Earth, forced by an ice age, pollution or a meteorite to find a new home elsewhere in the galaxy. The difficulties are daunting, humans evolved to live on Earth, not in space. We meet the scientists who are making journeys to Mars and beyond possible.

    The first task is finding the right planet; humans need oxygen and water, so not any old earth will do. We meet David Miller, the MIT scientist who works on the Terrestrial Planet Finder project and thinks it will make the job of finding a new home a whole lot easier. The ‘TPF’ is a set of orbiting satellites which can spot Earth-like planets and reveal whether they have a ‘human-friendly’ atmosphere.

    Once we’ve found a target, there’s the small matter of getting there. Just traveling to Mars and back is likely to take years. Journeys to stars are likely to be decades if not centuries. We look at some of the concepts to come out of NASA’s propulsion labs, from solar sails to antimatter.

    But even the rocket scientists can’t make our ship break the speed of light; we have to accept that crews are going to have to be in this for the long haul. We meet scientists who are trying to ensure that they arrive at their destinations healthy and ready to start life on a new planet.

    At MIT, we see centrifuges that mimic the effects of gravity, installed in a spaceship they might stop the crippling loss of muscle and bone mass that would threaten our astronauts. Dava Newman demonstrates her revolutionary design for a spacesuit on a climbing wall, made of the flexible material it will work with the wearer unlike the bulky suits currently used. We also reveal the work being done to overcome the deadly effects of cosmic radiation that threatens to wreck our crew’s DNA.

    We also look at the work being done to keep our crew in sound mind. Sealed in a ship for years with only faint communications with Earth they may rely on the software being designed by David Dinges, which allows a computer to spot when humans are becoming stressed.

    Eventually, though we may have to accept that more drastic changes are needed before we can leave for the stars. From hibernation pods to methods to slow down aging, the world of science fiction may have to become fact before we can go our solar system. And if we embrace genetic manipulation to redesign ourselves for space, we may also have to change our ideas of what a human is.

  • The Origin Of The Universe And The Solar System - Planets Beyond our Solar Syst Discovery Channel HD


    The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.

  • Exploring and Understanding our Universe - Solar System The Secrets of the Universe Documentary


    Using ESO’s Very Large Telescope (VLT), a team of astronomers have been able to detect the telltale spectral fingerprint of water molecules in the atmosphere of a planet in orbit around another star. The discovery endorses a new technique that will let astronomers efficiently search for water on hundreds of worlds without the need for space-based telescopes.

    Dr. Jayne Birkby of Leiden University presented the new result on Friday 5 July at the RAS National Astronomy Meeting in St. Andrews, Scotland.

    Since the early 1990s scientists have found almost 1,000 planets in orbit around other stars. These so-called exoplanets are mostly much larger than the Earth and many are much closer to their stars than we are to the Sun, leading them to be described as ‘hot Jupiters’. In the new work the team studied the exoplanet HD 189733b, a world that orbits its star every 2.2 days and is heated to a temperature of over 1,000 degrees Celsius.

  • Could The Universe Be Infinite? Secrets of a Dark Universe Documentary


    13.8 billion years ago, the Universe began with the hot Big Bang. It's been expanding and cooling ever since, up through and including the present day. From our point-of-view, we can observe it for some 46 billion light years in all directions, thanks to the speed of light and the expansion of space. Although it's a huge distance, it's finite. But that's just the part we can see. What lies beyond that, and is that possibly infinite? Adam Stephens wants to know:

    The farther away we look in any direction, the farther back in time we see. The nearest galaxy, some 2.5 million light years away, appears to us as it was 2.5 million years ago, because the light requires that much time to journey to our eyes from when it was emitted. More distant galaxies appear as they were tens of millions, hundreds of millions or even billions of years ago. As we look ever farther away in space, we see light from the Universe as it was when it was younger. So if we look for light that was emitted 13.8 billion years ago, as a relic of the hot Big Bang, we can actually find it: the cosmic microwave background.

    'Habitable' Exoplanets Might Not Be Very Earth-Like After All

    One of the most exciting moments in exoplanet science came in late February, when NASA's Spitzer Space Telescope announced the discovery of seven rocky planets orbiting in or near the habitable zone of their parent star, TRAPPIST-1, which lies 40 light years away from Earth.
    'The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system,' NASA said in a statement.

    The Electromagnetic Spectrum

    The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes - the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.

    Truth Behind the Photos: What the Hubble Space Telescope Really Sees

    When Hubble beams down images, astronomers have to make many adjustments, such as adding color and patching multiple photos together, to that raw data before the space observatory's images are released to the public. Hubble doesn't use color film (or any film at all) to create its images. Instead, it operates much like a digital camera, using what's called a CCD (charge-coupled device) to record incoming photons of light.

    ‘The Milky Way galaxy has died once before and we are now in what is considered its second life,’ the university announced in a statement. ‘Stars formed in two different epochs through different mechanisms. ‘There was a long dormant period between when star formation ceased. Our home galaxy has turned out to have a more dramatic history than was originally thought.’ A scientist called Masafumi Noguchi calculated the evolution of the Milky Way over the past 10 billion years.

  • Are Wormholes Real? With Dr. Dejan Stojkovic


    Wormholes are theoretical structures linking together two points in spacetime. Dr. Dejan Stojkovic and De-Chang Dai paper, Observing a wormhole, theorizes that by observing the motions of stars around a supermassive blackhole it can be determined if a traversable wormhole exists in our universe.

    Can we travel through wormholes?

  • A Brief History of the Universe: Crash Course Astronomy #44


    Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when the Universe was incredibly dense and hot. It expanded and cooled, going through multiple stages where different kinds of matter could form. It underwent a phenomenally rapid expansion called inflation, which smoothed out much of the lumpiness in the matter. Normal matter formed atoms between 3 and 20 minutes after the bang, and the lumps left over from inflation formed the galaxies and larger structures we see today.

  • Why we might be alone in the Universe


    There are trillions upon trillions of stars and worlds in our Universe. Faced with such large numbers, it's tempting to conclude that there must surely be other life out there, somewhere.

  • Life in the universe | The Economist


    Does life exist anywhere else in the universe? And how did it get started? Scientists are seeking the answers in the cosmos, our solar system and right here on planet Earth.

    Subscribe NOW to The Economist:

    Is there life elsewhere in the universe? Anyone who has pondered the immensity of the cosmos has probably wondered at some time or another whether life exists beyond our planet?

    The search for life beyond Earth has been buoyed by recent discoveries made by NASA's Kepler telescope - it's looking for planets outside our solar system known as exoplanets. Kepler measures the brightness of distant stars and tracks a stars dimming when a planet passes in front. Up until 1995, exoplanets were purely theoretical - but scientists have since identified thousands of them.

    in July, NASA scientists announced the discovery of one of their most exciting exoplanets yet - Kepler-452B. Located some fourteen thousand light-years away the planet is in the habitable zone which means it's the right distance from its own Sun and also the right size to potentially be earth-like.

    There is a limit to how much we can learn about Kepler-452B because of its distance. NASA is launching the James Webb telescope in 2018 to find earth-like planets closer to home so they can study their atmospheres for bio signatures that would indicate the presence of life. But there's another way to learn more about distant planets beyond what the Kepler telescope can tell us, and that is to look for signs of intelligent life.

    Frank Drake has been listening out for signals of intelligent life elsewhere in the universe for over 50 years. Mr Drake came up with something called the Drake Equation which is a mathematical formula that estimates how many advanced civilizations capable of transmitting signals might exist in the universe. He co-founded the SETI Institute, the search for extraterrestrial intelligence. Scientists at the SETI Institute have been searching for intelligent life for the past few decades.

    SETI researchers have not come across any signals yet but they say this is to be expected. SETI's efforts recently got a huge boost with a launch of breakthrough Listen, overseen by Martin Rees, Stephen Hawking, and Frank Drake and funded by Silicon Valley entrepreneur Yuri Milner. The project will greatly expand the organization's capacity to search and sift through data. But scientists aren't only interested in discovering life forms light-years away. At first glance our solar system seems like a rather unlikely place to find life beyond Earth but the reason scientists think it is plausible is because of the discovery of a group of organisms called extremophiles that live on earth.

    Scientists are looking at the moons of Jupiter and Saturn as well as our nearest neighbor Mars. The hope is that if we find further life in our solar system on places like Mars, we will improve our understanding of how easily it might have started elsewhere. But there is another way to answer this question - determining how it started on earth.

    One man who is trying to come up with an answer to this question is Jack Szostak. In his lab at Harvard University he's trying to determine how easy it is to create life by making it himself. Modern cells are intricate nano scale factories stuffed with thousands of different chemicals each taking part in a complicated and messy web of reactions. Long strands of DNA and codicils genetic information. Shorter strands of RNA carry that information around the cell telling it how to manufacture the proteins that run the chemical reactions it requires to live. It seems unlikely that these systems all evolved at the same time. At the Szostak lab they're focused on two experiments. One to work out how primitive cell membranes could grow and divide into daughter cells, and the other on RNA replication.

    Dr Szostak and his team have already created a protocell from a blob of lipids which contains RNA. The sticking point at the moment is working out how to make RNA that can copy itself without relying on a helping hand from RNA enzymes. If it is a difficult process reliant upon various bits of luck or circumstance then it is possible that we are a cosmic fluke - one that isn't going to be repeated elsewhere. But if experiments like Dr Szostak show that life emerges easily, then the odds of life appearing elsewhere in the universe look more likely.

    Perhaps one day when we're looking into the night sky we'll finally know the answer to the question are we alone?

  • The Beginning and Evolution of the Universe - How to Search for Exoplanets Documentary


    We are entering a new era in research. The synergy of technological advancement and scientific discovery enables a new approach to solving the universe's greatest mysteries. Through the world of particle physics, we see the great machines and the global collaborations working together in a unified quest. A diversity of people, a diversity of machines.

    Theoretically, in a Universe where the density of matter is high, clusters of galaxies would continue to grow and so, on average, should contain more mass now than in the past.

    Most astronomers believe that we live in a low-density Universe in which a mysterious substance known as ‘dark energy’ accounts for 70% of its content, and therefore, pervades everything.

  • How the Universe Works - Black holes - Space Discovery Documentary


    A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed.In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

  • Paul Horowitz: The Search for Extraterrestrial Intelligence | Talks at Google


    Paul Horowitz visited Google's office in Cambridge, MA to discuss the SETI (Search for Extraterrestrial Intelligence) project at Harvard University.

    Establishing an electromagnetic communications link across a thousand light-years presents unique technological challenges. In his talk, Prof. Horowitz visits some highlights of the science and technology of SETI -- Do THEY exist? Is communication possible? What is the best way? Is this just completely insane? -- and describes interesting searches his project and others have been doing.

    Paul Horowitz is a Research Professor of Physics and of Electrical Engineering at Harvard, and is co-author of The Art of Electronics.

    SETI at Harvard was supported in part by grants from NASA, The Planetary Society, and the Bosack/Kruger Charitable Foundation.

    A major quest of astronomers during past 30 years has been to discover exoplanets and how they form. One strategy is to search for lots of young stars still surrounded by protoplanetary disks and debris disks. These clouds of gas, rock, ice and dust are the same type of environments that gave rise to our solar system. By looking for these environments we have a chance to find planetary habitats.

  • The Loneliest Galaxies in the Universe - Mia de los Reyes - 5/8/2020


    There are vast voids in our universe inhabited by only a handful of small dwarf galaxies. Come learn how the formation and characteristics of these dwarf galaxies can tell us important things about galaxy evolution and cosmology as a whole. Start: 0:18; Lecture: 6:32; Expert Q&A Panel: 42:22

    Date: May 8, 2020
    Lecturer: Mia de los Reyes
    Title: The Loneliest Galaxies in the Universe
    Abstract: Most of the matter in the universe is located in long and thin structures called cosmic filaments that stretch across the universe in web-like formations. However, some galaxies live in the much emptier spaces between cosmic filaments, called cosmic voids. By comparing the chemical makeup of void galaxies and filament galaxies, we can learn about how galaxies' environments shape their formation and evolution.

    Q&A Panelists:

    --Mia de los Reyes is a third-year PhD student in Astronomy at Caltech. She studies the chemical composition of small galaxies near the Milky Way. When not confined to her own home, she enjoys rock climbing and aerial silks; given the current state of the world, she's gotten really into cross-stitching and has also started watching Star Trek for the first time. She really hopes you like this talk.

    --Dr. Cameron Hummels is a postdoctoral researcher in theoretical astrophysics at Caltech. He creates supercomputer simulations to study the formation and evolution of galaxies since the Big Bang.

    --Max Goldberg is a first-year PhD student in Astronomy at Caltech. He studies the orbital dynamics and formation of systems of planets around other stars.

    --Nitika Yadlapalli is a second-year PhD student in Astronomy at Caltech. She’s interested in instrumentation in astronomy and currently works on commissioning a new radio telescope at the Owens Valley Radio Observatory.

    --Shreyas Vissapragada is a third-year PhD student in Planetary Science at Caltech. He’s interested in observations of planetary evolution and is currently focused on studying atmospheric escape and orbital dynamics.

    -- Dillon Dong is a fourth-year PhD student in Astronomy at Caltech. He uses radio and optical telescopes to study the birth and death of massive stars.

  • Where is the Origin of Life on Earth?


    To answer the iconic question “Are We Alone?”, scientists around the world are also attempting to understand the origin of life. There are many pieces to the puzzle of how life began and many ways to put them together into a big picture. Some of the pieces are firmly established by the laws of chemistry and physics. Others are conjectures about what Earth was like four billion years ago, based on extrapolations of what we know from observing Earth today. However, there are still major gaps in our knowledge and these are necessarily filled in by best guesses.

    We invited talented scientists to discuss their different opinions about the origin of life and the site of life’s origin. Most of them will agree that liquid water was necessary, but if we had a time machine and went back in time, would we find life first in a hydrothermal submarine setting in sea water or a fresh water site associated with emerging land masses?

    Biologist David Deamer, a Research Professor of Biomolecular Engineering at the University of California, Santa Cruz, and multi-disciplinary scientist Bruce Damer, Associate Researcher in the Department of Biomolecular Engineering at UC Santa Cruz, will describe their most recent work, which infers that hydrothermal pools are the most plausible site for the origin of life. Both biologists have been collaborating since 2016 on a full conception of the Terrestrial Origin of Life Hypothesis.

    Lynn Rothschild, Senior Scientist at NASA’s Ames Research Center and Adjunct Professor of Molecular Biology, Cell Biology, and Biochemistry at Brown University, who is an astrobiologist/ synthetic biologist specializing in molecular approaches to evolution, particularly in microbes and the application of synthetic biology to NASA's missions, will provide an evolutionary biologist’s perspective on the subject.
