Signs of Life discovered on Venus and atmosphere
On the other hand, we may have instead found evidence of a new abiotic form of phosphine synthesis— I expect scientists will be working hard to propose non-biological processes that could explain these results. I also expect some new Venus probes real soon now.<p>This definitely could be the result of an unknown abiotic process. It also definitely could be evidence of life.<p>Some papers to check out:<p>- <a href="https://arxiv.org/abs/1910.05224" rel="nofollow">https://arxiv.org/abs/1910.05224</a><p>- <a href="https://www.liebertpub.com/doi/10.1089/ast.2017.1783" rel="nofollow">https://www.liebertpub.com/doi/10.1089/ast.2017.1783</a><p>For 3 billion years, ending about 750 million years ago, Venus was likely hospitable, leaving the tantalizing possibility that we’ve detected the last vestiges of an ancient ecosystem.<p>Self-promotion: we'll cover this in-depth in Orbital Index (<a href="https://orbitalindex.com" rel="nofollow">https://orbitalindex.com</a>) this week.
