Planet Venus, life discovered?


This 14 September 2020 video from Columbia University in the USA says about itself:

Did We Just Detect Life on Venus?

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.

An ‘extraordinary’ find in the clouds of Venus could point to the presence of life

Scientists say they’ve detected a gas called phosphine in the atmosphere of Venus—a gas thought to be impossible to make on planets like Earth or Venus without the presence of life. If this finding is confirmed, one of two possibilities could exist on the planet long considered Earth’s twin: an exotic chemistry we don’t understand; or life.

LIFE ON VENUS? Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet. Two telescopes in Hawaii and Chile spotted in the thick Venutian clouds the chemical signature of phosphine, a noxious gas that on Earth is only associated with life, according to a study in Monday’s journal Nature Astronomy. Several outside experts — and the study authors themselves — agreed this is tantalizing but said it is far from the first proof of life on another planet. [AP]
