This study explores the capabilities of the upcoming Extremely Large Telescope (ELT) and its ANDES instrument in analyzing the atmospheres of young, distant planets similar to Neptune but smaller. By simulating observations of the exoplanets V1298 Tau b and TOI-451 c, researchers demonstrated that we will soon be able to detect water, hydrogen sulfide, and carbon monoxide on these worlds. The research highlights that by carefully comparing data from when a planet is passing in front of its st...
