Solar Orbiter Makes Its First Venus Flyby
The NASA/ESA Solar Orbiter spacecraft is on its way to the sun. But in the morning of Dec. 27, the probe reached its closest approach to Venus at around 7:39 AM Eastern time when the spacecraft was about 4,700 miles (7,500 kilometers) from the top of the planet's cloud tops.

Life on Venus? Or much ado about nothing?
For decades, we thought of Venus as a completely uninhabitable planet because of the hellish environment on its surface. Yet, several scientists have championed the idea that life could exist in the thick cloud decks that shroud the planet. Several weeks ago, a team of astronomers reported the detection of phosphine on Venus. If this stinky, toxic, perhaps biogenic gas does exist on Venus as reported, we stand to learn something profound. If clever chemists succeed in identifying a nonbiological source that produces phosphine, we will learn about the limitations of using atmospheric biosignatures to infer life. If they fail, this discovery increases our already high motivation to go to Venus and study its atmosphere in situ with 21st-century instruments. To discuss this amazing discovery and its consequences for the search for life beyond Earth, we invited two astronomers: Clara Sousa-Silva, co-author of the study about phosphine on Venus and David Grinspoon, astrobiologist and member of the SETI Institute’s Science Advisory Board, and is part of the Breakthrough Initiative and co-investigator on multiple proposed missions to search for primitive life in the clouds of Venus. The speakers will discuss whether or not phosphine detected on the planet next door is a signature of alien biology and how we might one day send a space probe to find out. #SETITalks #Venus #SearchForLife
Venus Death of a Planet 4k
Billions of years ago, our nearest planetary neighbor, Venus, may have harbored lakes, oceans, and life-giving habitats similar to those on the early Earth. Today, Venus spins slowly in a backward direction. It's a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists have come to see Venus as the alien planet “next door,” a laboratory for testing ideas about how planets evolve and the challenges they face in nurturing life. They are now unveiling daring new strategies to reach down to its hostile surface. From floating bases stationed high in Venus’ atmosphere, they hope to send down new generation probes to search for clues from a time when the planet was alive. How did Venus descend into this hellish state? And how did its sister planet, Earth, manage to survive?

Venus May Have Life!
Check Out Overview of PBS Terra: https://bit.ly/33otrUn If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric acid rain. And yet it may have just jumped to the front of the pack. In fact, we may have detected the signature of alien life - Venusian life -for the first time.

StarTalk Podcast: Cosmic Queries – Life on Venus, with Neil deGrasse Tyson
Is there life on Venus? Neil deGrasse Tyson, comic co-host Paul Mecurio, and astrobiologist David Grinspoon investigate the recent discovery of phosphine gas in Venus’s atmosphere and answer your Cosmic Queries. We gathered up all your Cosmic Queries about the recent news and we start with the big question: Does this mean there’s life on Venus? Could there be a habitable zone? David tells us why the answer is…maybe. We explore the discovery of the phosphine gas and the possible explanations behind its existence in Venus’s atmosphere. You’ll explore what’s next after a discovery like this. Can we bring samples back to Earth? David gives details on the complexity of a mission to the Venusian atmosphere. We also explore Venus’s volcanoes and its geologically-active surface. David explains why, if we want to know what’s going on in the atmosphere, we have to know what’s happening on the surface. Then, we take a look at Earth: Can we use Earth to help us deduce what’s happening on Venus? We ponder the best way to search for life in the universe. We also ponder whether life needs water to thrive or if life just needs liquid. David gives us the top three gases that could be used to signify life elsewhere. Find out why Venus’s atmosphere is so thick. We discuss Venus’s runaway greenhouse effect and the viscous circle of its carbon cycle. We also wonder if a probe from Earth might have introduced microbes to Venus’s atmosphere. All that, plus, we ask the very important question: Is the Wicked Witch of the West actually from Venus?

Did Humans Live On Venus Before Earth? | Unveiled
Scientists have found signs of potential life on Venus, but what does the discovery mean for the search for alien intelligence? In this video, Unveiled uncovers how Earth's evil twin might've once hosted wide oceans and pleasant temperatures, enough even to support human life. But could humans ever, really, have existed on the next-closest planet to the sun?? This is Unveiled, giving you incredible answers to extraordinary questions!

SETI Live: Is there life on Venus?
Researchers from Cardiff University and MIT just published a paper in Nature in which they claim to have found phosphine, a possible biosignature, in the clouds of Venus' atmosphere. Join David Grinspoon, astrobiologist at the Planetary Science Institute who serves on the SETI Institute's Science Advisory Board, and Nathalie Cabrol, Director of the Carl Sagan Center at the SETI Institute, in a discussion about the possibility of life on Venus.
Big Picture Science: Life on Venus? - Sept 14, 2020
http://bigpicturescience.org/episodes/life-on-venus Possible biosignature detected - Have scientists found evidence of life on Venus? Known for its scorching temperatures and acidic atmosphere, Earth’s twin hardly seems a promising place for living things. But could a discovery of phosphine by researchers at MIT point to a high-altitude biosphere on this nearby world? Guests: Clara Sousa–Silva https://clarasousasilva.com/ - Research scientist in MIT's Department of Earth, Atmospheric and Planetary Sciences. She and Sara Seager co-authored a paper in January 2020 titled, “Phosphine as a Biosignature Gas in Exoplanet Atmospheres” https://www.liebertpub.com/doi/abs/10.1089/ast.2018.1954 Sara Seager https://web.mit.edu/physics/people/faculty/seager_sara.html - Professor of physics and planetary science, Massachusetts Institute of Technology and author of “The Smallest Lights in the Universe” https://www.amazon.com/gp/product/0525576258/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=arweal-20&creative=9325&linkCode=as2&creativeASIN=0525576258&linkId=56235bf81fc02a5e6fa0fc7f8f1cfd1c Nathalie Cabrol https://www.seti.org/our-scientists/nathalie-cabrol - Planetary Scientist and Director of the Cal Sagan Center at the SETI Institute David Grinspoon https://www.psi.edu/about/staffpage/grinspoon - Senior Scientist at the Planetary Science Institute, author of “Earth in Human Hands.” https://www.amazon.com/gp/product/1455589128/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=arweal-20&creative=9325&linkCode=as2&creativeASIN=1455589128&linkId=9a351ab8fc236524366cad0e8be566e2 Segments:

Did we find life on Venus?
Senior Planetary Astronomer Franck Marchis tells us the story of the search for life on Venus and the importance of today's discovery of a biomarker in the atmosphere of the planet. Could this indicate that Venus has an aerial biosphere? What are the consequences for the future exploration of the hellish sister of Earth?
RAS Press Briefing - Phosphine on Venus
The Royal Astronomical Society press briefing held on 14 Sep 2020, discussing the detection of phosphine in the cloud decks of Venus. See https://ras.ac.uk/news-and-press/news/hints-life-venus for full details of the discovery.
