NASA’s James Webb detects chemistry of an exoplanet’s atmosphere that could help find aliens
NASA’s James Webb Space Telescope (JWST) could be a significant player in the search for alien life after it successfully revealed the makeup of an exoplanet’s atmosphere in never before seen detail. JWST’s powerful instruments captured atoms and molecules, along with signs of active chemistry and clouds – features Hubble and Spitzer were unable to detect when they observed the planet and those that hold evidence of signs of life. Astronomers used WASP-39b, a hot Saturn 700 light-years away from Earth, to test the telescope’s capabilities, and the telescope used its infrared capabilities to pick up colors chemical fingerprints that cannot be detected in visible light.
