Q&A 129: Did Life Get a Ride to Venus from our Missions? And More...
Did Venus life hitch a ride on the Venera missions? Could we use life to terraform Venus? Life on Venus? Booooring. 00:00 Start
00:16 Did we infect Venus with life?
02:27 Can we terraform Venus with bacteria?
04:03 This is boring.
06:21 It's probably not life.
09:07 Phosphine is on Jupiter too.
10:50 Are there spaceflight insurance companies?
12:59 Why can gas giants remain spherical?
15:21 What if the Moon was in geosynchronous orbit?
17:42 Are astronauts falling?
19:40 Could we use interstellar hydrogen as fuel?
22:52 Could supermassive black holes be primordial black holes?
26:25 Are there rogue intergalactic stars? Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here. Our Book is out!

Can Life Spread From Star to Star? The Theory of Galactic Panspermia
The race is on to find life in other places in the Solar System, from underground reservoirs on Mars to the subsurface oceans on Europa and Enceladus. If spacecraft, rovers or even astronauts make the momentous discovery of life on another world, that’ll just open up new questions. Did it originate all on its own, completely independently from Earth, or are we somehow related? And if we are related, how long ago did our evolutionary trees branch away from each other. Even though Mars is millions of kilometers away, it could be possible that we’re still related thanks to the concept of Panspermia; the idea that meteor impacts could transfer rocks and maybe even living creatures from world to world. But could you go one step further? If we find life on another star system, could we discover that we’re actually related to them too? Is Galactic Panspermia possible? Our Book is out!

The Fermi Paradox & Panspermia
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we'll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true. Visit our Website: http://www.isaacarthur.net

Seeding the Stars
Sign up with Skillshare for 2 months of Free classes: https://skl.sh/isaac5
The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long. Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars. Visit our Website: http://www.isaacarthur.net

'Oumuamua Is Not Aliens
https://www.youtube.com/watch?v=wICOlaQOpM0&t=455s Hosted by Matt O'Dowd
Written by Matt O'Dowd
Graphics by Luke Maroldi
Assistant Editing and Sound Design by Mike Petrow Made by Kornhaber Brown (www.kornhaberbrown.com) Life existing on Earth is odd. The oldest fossils are now dated to only a few hundred million years after the moment Earth first became habitable. Is it really reasonable to imagine that evolution turned an unliving chemical soup into the first true living cells in that geological eye-blink? Well, maybe. But the discovery of the early appearance of life on Earth was definitely a big “huh, that’s weird” moment. And it’s inspired some creative thinking. For example, what if the first genesis of life – abiogenesis – is actually incredibly unlikely – so unlikely that it only happened once in the entire galaxy. And that “once” was not on Earth. What if primitive life arrived on Earth after having traveled vast distances across the Milky Way. Some scientists think this is the case. This is the Panspermia hypothesis.

PSW 2399 Comets and the Origin of Life | Steven Squyres
PSW #2399
November 2, 2018
Lecture Starts at 11:00
www.pswscience.org Comets and the Origin of Life
The Proposed CAESAR Mission to Return a Comet Sample to Earth Steven W. Squyres
James A. Weeks Professor of Physical Sciences
Cornell University Comets are among the oldest and most interesting objects in the solar system. Learning about them can tell us a great deal about the origins and formation of the solar system, and perhaps about the origin of life. For example, researchers have speculated that tholin-rich comets may have seeded earth with organic compounds early in its development, stimulating life to begin. The Rosetta mission studied the comet 67P/Churyumov–Gerasimenko at close range for two years. The trove of information from Rosetta provides a highly detailed basis for designing a sample return mission to this comet. And the detection of tholins on 67P/Churyumov–Gerasimenko make it an extremely attractive object for further study, with the promise of illuminating how life began. The Comet Astrobiology Exploration Sample Return Mission (CAESAR) is a proposed mission back to 67P/Churyumov–Gerasimenko to sample the comet and bring the samples back to earth. Currently, it is one of a pair of finalists selected for further concept development in NASA’s New Frontiers Program. The other is the Dragonfly mission to Titan. If CAESAR is selected, and things go smoothly, it will launch in 2024 and return samples to Earth in 2038. This lecture will discuss the reasons for visiting 67P/Churyumov–Gerasimenko again and bringing samples of the comet back to earth for detailed study, and the engineering and science mission proposal being developed. Steven Squyres is James A. Weeks Professor of Physical Sciences at Cornell University. Before joining the Cornell faculty, he was a postdoctoral associate and research scientist at NASA Ames Research Center. Concurrently, Steve is the Principal Investigator for the Mars Exploration Rover Project, a co-investigator on Mars Express and for the Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment, a member of the Gamma-Ray Spectrometer Team for Mars Odyssey, and a member of the Cassini imaging team. Previously, he was an associate of the Voyager imaging science team, radar investigator on the Venus Magellan mission, member of the Mars Observer gamma-ray spectrometer team, and co-investigator on the Russian Mars ’96 mission. Steve’s research focuses on the robotic exploration of planetary surfaces, the history of water on Mars, geophysics and tectonics of icy satellites, tectonics of Venus, planetary gamma-ray and x-ray spectroscopy. Research for which he is best known includes study of the history and distribution of water on Mars and of the possible existence and habitability of a liquid water ocean on Europa. Among other awards, Steve is the recipient of the Carl Sagan Memorial Award, the Carl Sagan Medal for Excellence in Communication in Planetary Science, the Mines Medal, the AAU’s Urey Prize and the Franklin Institute’s Franklin Medal in Earth and Environmental Science. He is an author on numerous technical papers, and the book, Roving Mars. He has appeared often in the media speaking on space and space exploration. Steve earned a BA in Geological Sciences and a PhD in Astronomy from Cornell University, where he worked closely with Carl Sagan.
Panspermia
Subscribe to Naked Science – http://goo.gl/wpc2Q1 Did comets bring water, organic material, or even life itself to Earth? Panspermia is the controversial hypothesis that life exists throughout the Universe, distributed by meteoroids, asteroids, comets, planetoids, and also by spacecraft in the form of unintended contamination by microorganisms.

Is The Octopus An Alien? | Mach | NBC News
The octopus certainly does look strange, with bugged-out eyes, suction-cup tentacles, and the ability to change color for camouflage. But a new paper in a peer-reviewed scientific journal posits that octopuses aren’t just strange: They are ALIENS. Literally.

Panspermia: Life From Space
We tend to assume that life began here on Earth. But it’s possible that life originated on an alien world and in some form or another was brought here. In this video, we discuss the possibility that life originated somewhere else, either on a planet or asteroid, then spawned life here on Earth. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1

Panspermia is the radical theory that life on Earth came from Mars
Astronomer and director of the multidisciplinary Columbia Astrobiology Center at Columbia University, Caleb Scharf, spoke to us about a interesting idea that has plagued scientists for decades: Did life on Earth actually originate on Mars? How is this possible? Scharf explains. You can learn more from Scharf by reading his latest book "The Copernicus Complex."

"The Philae space probe was powered down earlier than expected, but not before an instrument discovered an organic compound that was first detected in the comet's atmosphere, the Wall Street Journal exclusively reported Monday. The find is extraordinary considering the organic compound contains the carbon atom, which is the basis of life on planet Earth." Origin Of Life: The Panspermia Theory
https://helix.northwestern.edu/article/origin-life-panspermia-theory
"How life originated on earth is a question that people have pondered for ages. Theories abound, from those based on religious doctrine, to the purely scientific, to others that border on science fiction. One possibility that hovers on this border is the panspermia theory, which suggests that life on Earth did not originate on our planet, but was transported here from somewhere else in the universe." 'Necropanspermia' Suggested As A Way Of Seeding Life On Earth
http://phys.org/news/2010-11-necropanspermia-seeding-life-earth.html
"Panspermia is a mechanism for spreading organic material throughout the galaxy, but the destructive effects of cosmic rays and ultraviolet light tend to mean most organisms would be destroyed or arrive on a new world broken and dead. Now Paul S. Wesson, a visiting researcher at the Herzberg Institute of Astrophysics in Canada, suggests the information contained within damaged organic material could seed new life. He terms this process necropanspermia." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!
