Kelly Lepo | I am glad this is finally up! We are now more than 18 months into # JWST science operations. How have astronomers used JWST to study exoplanets? What have we learned from all this beautiful new data about planets around other stars?

Kelly Lepo | Science Highlights from the # JWST town hall at # AAS243 : - More than 700 JWST papers published so far. - JWST found thousands of galaxies in the early universe, which are brighter and more numerous than expected. - There are a lot of active supermassive black holes in the early universe, which may require massive seeds. - Detecting molecules in the atmospheres of giant exoplanets is easier than expected, but the atmospheres of rocky planets are hard to measure.
