The James Webb Space Telescope has spotted signs of a ghostly aurora over a 'failed star,' in the form of infrared emissions from methane in the brown dwarf's atmosphere.
NASA's James Webb Space Telescope has made a surprising observation, detecting aurorae on a cold, lonely brown dwarf known as W1935.
The new discovery by NASA’s James Webb Space Telescope (JWST) has left the scientists baffled with the mysteries of brown dwarf and auroral processes. The JWST found a new brown dwarf, which is an object that is much larger than gas giants like Jupiter but smaller than a star. NASA has discovered many brown dwarfs in the past, but this one is different.
