地球外的生命痕跡

Searching for life beyond Earth means looking past familiar signs like oxygen and instead focusing on complex chemical fingerprints. The presence of phosphine, a toxic and foul-smelling gas, in places like Venus’s clouds and Earth’s swamps suggests it could signal life where oxygen is scarce. However, no single molecule is enough—detecting life will require recognizing intricate networks of interacting gases. As technology advances, the real challenge is ensuring we do not miss the subtle signs of alien biospheres when they finally appear.
