LINKS: Discovered Exoplanets

~~~NASA has this page briefly profiling some of the discovered planets beyond our solar system. As of Dec 30 2022, there are 5,235 Exoplanets detected:

~~~The detection of Exoplanets has been done by discerning them transiting in front of stars from our position. There is a dip in light seen as it transits. So far, direct images have been very rare:

~~~The James Webb Space Telescope has detected it's first exoplanet and atmosphere spectrum analysis of elements expected this summer (likely no life despite size of earth, is several hundred degrees warmer, a factor already discerned):

~~~Water vapor has been detected from either red dwarf star or a closeby rocky planet (at 800 degrees likely too hot for life):

~~~TESS (Transiting Exoplanet Survey Satellite) detects rocky, earth-size planet around star 90 light years distant; many volcanoes may create atmosphere and have at least microscopic life due to water vapor:
