Scientists have discovered that a thick atmosphere of carbon dioxide could be present on a newly discovered exoplanet. This is unusual, as carbon dioxide is not usually found in significant amounts in the atmospheres of other exoplanets. The planet, called K2-18b, is located about 111 light-years away and is the first known super-Earth to have both water and carbon dioxide in its atmosphere. This discovery was made possible by data collected by the James Webb Space Telescope, which was launched in 2023. This is a groundbreaking discovery in the field of exoplanet research, and could lead to further discoveries about the atmospheres of other exoplanets.
