From Deborah Byrd at Space:

Living earthly microbes inhabit virtually every nook and cranny of our world, including extremely harsh environments like Yellowstone’s hot springs, deep ocean hydrothermal vents and the toxic sludge of polluted areas. Earthly bacteria have also been identified, alive, as high in our atmosphere as 25 miles (40 km) up. Neighboring Venus is a hostile world. Heat trapped by its dense atmosphere makes it hot enough on its surface to melt lead. But a series of space probes – launched between 1962 and 1978 – showed that temperatures and pressures at comparable heights in Venus’ atmosphere (25 miles or 40 km up) don’t preclude the possibility of microbial life. Now an international team of researchers has laid out a case for the atmosphere of Venus as a possible niche for extraterrestrial microbial life. More.

Question: Doesn’t life – if it really exists – shout out louder than this?
