"To record their findings, a team of scientists analyzed light from K2-18 b's parent star as it passed through the exoplanet's atmosphere. That tiny fraction of starlight eventually reaches telescopes like Webb, leaving traces that astronomers can piece together to determine the gases of the exoplanet's atmosphere, NASA said."
forget the alien talk, the fact that we can point a telescope at a star 120 light years away, have that starlight pass through the tiny sliver of the atmosphere of a planet that happens to pass in front of that star, capture that light, identify that it is different from the rest of the miniscule amount of starlight captured, and identify what elements make of the atmosphere of the planet if pretty fucking bonkers. maybe we are the crazy high tech aliens we see in sci-fi movies...
