Helium detected escaping from rocky exoplanet's atmosphere
Scientists have detected helium being stripped away from the atmosphere of a large, rocky exoplanet. This marks a significant observational milestone in the study of planetary atmospheres beyond our solar system. The detection of escaping helium allows researchers to draw inferences about the remaining atmospheric composition of the planet. Such findings help astronomers better understand how planetary atmospheres evolve and erode over time under stellar radiation.
