NASA’s Webb Maps Weather on Planet 280 Light-Years Away
Space Telescope Science Institute (STScI)Sometimes not finding something is just as exciting and useful as finding it. Take hot Jupiter WASP-43 b, for example. This tidally locked world has a searing hot permanent dayside and a somewhat cooler nightside. Astronomers using Webb to map the temperature and analyze the atmosphere around the planet expected to detect methane, a common carbon molecule, on the nightside.
