🪐 In the search for aliens, astronomers sometimes look for atmospheric "biosignatures"—chemical signs of life such as oxygen, methane, or ozone—in the atmospheres of exoplanets like TRAPPIST-1e. Using telescopes like Hubble and the James Webb Space Telescope, scientists scan the light passing through these distant planets' atmospheres to spot unusual chemical mixes that might hint at biological activity beyond Earth. ✨ #aliens⚡#biosignatures⚡#exoplanets⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
