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.

Earth will be in Venus situation in the future due to the movement of the solar system's habitable zone while the sun will expand it.s volume. Also Venus is not suitable for life in the future.

I am always excited for any new discoveries we make in the world of astronomy. So yes! Very excited at the newfound possibility of life on Venus!

Actually there is no detection of life in Venus's atmosphere, and there is not a detection of a biomarker in Venus's atmosphere -- it is a detection of phosphine. As far as we know, there is no known non-biological process that can produce those amounts of phosphine -- but we don't know high temperature chemistry good enough ... For me, this discovery is a discovery of phosphine, not life. Is there life on Venus? Perhaps.

Even we could have been from Venus billions of years ago when the sun was small and Venus was in the habitable and there might have been humans there who moved to earth when the sun became bigger

There is no actually proof of life on Venus or Mars. We have found or observed possible remains or byproduct of low level life which existed or currently does - not intelligent life! For me these discovers are over blown. The existence of such micro organisms shouldn’t really be shocking.. Until something of organic multi-cell is observed , stop making something small very large in importance.

Such arrogance. The discovery of ANY kind of life that isn't related to Earth's is monumental, and would open up a whole new branch of science based on an entirely unique biosphere. What kind of sick narcississm is it with people who won't be satisfied unless aliens turn out to look exactly like themselves? If they don't match up to some arbitrary technological benchmark, you'd think it was OK to use them like commodities, too, just because they can't defend themselves against our tech ... but then whine about what Europeans did to morons who were still playing with stone when they found them. Just like the attitude towards all non-human life on Earth. Independence Day was the most hypocritical movie I've ever seen; what right would YOU have to demand to be treated with respect by some species that doesn't look like you, talk like you, and sees human tech as something any dumb beast can do?

"Venus may have had a climate with liquid water on its surface for aproximately 2 billion years".....BWAHAHAHAHA..... "Elvis Presley may have lived on Saturnus and Ur-Anus for exactly 25 years 2 hours 3 minutes and 6 seconds... than he farted and moved to "Yo Momma House".....

I'm guardedly excited. Like your friend, I think the clincher for me will be a mission to Venus that actually confirms the presence of microbial life in the atmosphere, and we're going to have to do that anyway to answer your last question, "Are we related?" Just as you said, if we're not, then that is HUGE - it really will mean that life is commonplace in the universe. So, my "best possible outcome" here is that we go, we study, and we find microbes that are either 1) not based on DNA or 2) has a DNA signature so clearly distinct that we can't be related.

9:50 - They need to send a probe and bring back samples. We need to SEE microbes, do analysis on them, etc.

Lets send a prob to take its sample and examine it. "The shortest time a spacecraft has taken to get to Venus from Earth is 109 days, or 3.5 months. The longest journey took 198 days or 6.5 months. Most journeys take between 120 and 130 days which is about 4 months."

More chance of this virus disappearing tomorrow than finding life on Venus! As they say when I see it I'll believe it, not just talk shit an give your own prediction, next year life on the Sun,life in a black hole,

And further research revealed that in fact we came here from Venus after we stuffed the planet up. Then we stuffed this place up and this is in fact the second time around for us on earth but we are entering a third stuff up
