If life does exist on Venus, NASA may have first detected it back in 1978. But the finding went unnoticed for 42 years.
Life on Venus is still a long shot. But there’s reason to take the idea seriously. On Sept. 14, a team of scientists made a bombshell announcement in the journal Nature Astronomy: Using telescopes, they’d detected phosphine, a toxic gas long proposed as a possible sign of alien microbial life, in the upper part of the planet’s thick atmosphere. The detection was a landmark in the long hunt for life elsewhere in the solar system, which has mostly focused attention on Mars and a few moons orbiting Jupiter and Saturn. Meanwhile, Venus, hot and poisonous, was long considered too inhospitable for anything to survive.
