Astronomers Detect Biosignature Gas Phosphine in Atmosphere of Venus

Astronomers using the James Clerk Maxwell Telescope (JCMT) and the Atacama Large Millimeter/submillimeter Array (ALMA) have detected phosphine (PH3) gas in temperate but hyperacidic cloud decks of Venus. In Earth’s atmosphere, this gas is uniquely...

Astronomers Detect Biosignature Gas Phosphine in Atmosphere of Venus
Astronomers using the James Clerk Maxwell Telescope (JCMT) and the Atacama Large Millimeter/submillimeter Array (ALMA) have detected phosphine (PH3) gas in temperate but hyperacidic cloud decks of Venus. In Earth’s atmosphere, this gas is uniquely associated with anthropogenic activity or microbial presence. Studying the atmospheres of rocky planets gives clues to how they interact with [...]
