NASA's SPHEREx space telescope has observed 37 brown dwarfs, analysing the composition of their atmospheres, which contain clouds and methane. Brown dwarfs form like stars, from collapsing clouds of gas, but lack the mass to sustain hydrogen fusion, sharing traits with both stars and giant planets. The observations offer a clearer picture of how these objects sit between stars and planets, and are drawing interest from astronomy enthusiasts discussing the findings online.

NASA reports that its SPHEREx space telescope has observed a wide variety of brown dwarfs — objects larger than planets but too small to sustain hydrogen fusion like stars. The mission is cataloguing these dim objects in infrared light, offering new insight into how many brown dwarfs exist and how they form, a finding of note for astronomers.
