The James Webb Space Telescope detected methane and carbon dioxide in the atmosphere of K2-18 b
The James Webb Space Telescope (JWST) notched another astronomical achievement in its figurative belt: It discovered carbon-based molecules in the atmosphere of an exoplanet, a planet that is far outside our solar system. This is particularly significant because the exoplanet in question, K2–18 b, is believed to contain an ocean. The Hubble Space Telescope provided the research and observations that initially suggested K2–18 b has liquid water, making it by definition a so-called "Hycean" world. As a consequence, the…
