Data from the James Webb Space Telescope points to possible auroras on an isolated world near our Sun.
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission from a brown dwarf, an unexpected finding for such a cold and isolated world. The results were published in the journal Naturesuggests that this brown dwarf may produce auroras similar to those seen on Jupiter and Saturn, as well as on our planet.
Research on brown dwarfs
Larger than planets but lighter than stars, brown dwarfs are ubiquitous in our solar neighborhood, and thousands have been identified. Last year, Jackie Faherty, senior scientist and senior director of education at the American Museum of Natural History, led a team of researchers given time at JWST to study 12 brown dwarfs.
