Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon ...
Different isotopes of nitrogen in ammonia molecules on a distant brown dwarf could hold clues about how giant planets form. Astronomers now have a way to figure out how gas-giant planets form ...
Astronomers now have a way to figure out how gas-giant planets form, thanks to a discovery by the James Webb Space Telescope (JWST) of ammonia "isotopologues," which are molecules that contain the ...
