But telescopes have gotten so good now that astronomers can tell what the weather is like on planets hundreds of light-years away. Earlier this month, astronomers reported in a Nature…

A First Look At Rocky Exoplanets With JWST - Astrobiology

Rocky exoplanet characterization has been a top priority for early James Webb Space Telescope (JWST) science operations. Several milestones have been achieved, including the most precise rocky planet transmission spectra measured to date, and the first detection of thermal emission for rocky worlds below 800 Kelvin. Despite these advances, no atmospheres have been definitively detected. […] The post A First Look At Rocky Exoplanets With JWST app…
