The announcement of the detection of a possible biomarker in the atmosphere of Venus has shook up the field of astrobiology and grabbed headlines across the world. Today, we explore why Venus could plausibly host life, how this detection was made, and whether it really means that we've finally found extraterrestrial life. Written and presented by Prof Kipping, featuring guest Dr Caleb Scharf.

So if their life on Venus? Does that mean we can have 1 wife on Earth? and 1 wife on Venus? Or do i have to give up my future wife on Earth for a Venus wife? and will the homes be cheap to buy on Venus? I'm just Joking please don't take this comment serious

Sorry to burst everybody's bubble, but the answer is NO. All that's been found is up to 20 parts per BILLION of phosphine gas - PH3 - in some parts of the Venus atmosphere. This gas itself is colourless, odourless and very toxic. The Venus atmosphere is almost exclusively carbon dioxide, with clouds of sulphuric acid. No life can exist in it. The surface temperature is around 470C. And there is NO WATER. Venus winds at the surface blow at 360 km/hr, some 60 times the planet's rotation. The possibility of any life is zero, zip, nada. Even the authors of the study are not saying there is life there. Finally, gases on planets are not observed directly, of course, but are determined by spectroscopy - where different gas molecules absorb different wavelengths of light.

What if it’s bacteria from the Soviet probes that somehow multiplied until it became visible in Venus’s atmosphere? Just a thought, I know it’s not likely though.

Don't forget the ethical side of things. What if we sent a probe to Venus and it contaminated Venusian life? Changing their evolutionary pathway or even killing them off into extinction. And it later turns out this was the only other priceless lifeform in our Solar System and Universe.

Each planet moving away from earth is what's left of that planets life cycles, including now life. All that's left of Venus is life in the clouds. Temp is 30°c to 90°c. Habitable! WOW!

Actually, Clinton did not announce that life had been discovered on Mars. "Today, rock number 84-001 speaks to us across across all those billions of years and millions of miles. It speaks of the possibility of life. If this discovery is confirmed, it will surely be one of the most stunning insights into life science has ever uncovered." He put some mild emphasis on the word "possibility." frvid.com/video/vid%C3%A9o-pHhZQWAtWyQ.html

First time I have watched your stream channel, very well done in my opinion. Thoughtfully put together and a great interview too. You have obviously researched your information and are also as excited as I am about this discovery. I hope it turns out to be biologic, and a sample return mission to a level 4 lab on the space station (andromeda strain) where it could be researched in safety.
