NASA's Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

Thousands of exoplanets are known to orbit distant stars. Far fewer have had their atmospheres studied. The Webb telescope will bring new capabilities for determining atmospheric compositions, temperatures, and structures. Some of Webb’s earliest observations will focus on gas giants, whose puffy atmospheres should be easier to inspect. Lessons learned there will apply to later observations of small, rocky worlds.
