Artist’s concept of a brown dwarf floating in space. A large sphere with swirling crimson and orange clouds against a dark purple atmosphere dominates the center. Behind it, scattered stars and a hazy band of the Milky Way cross the black background diagonally from upper left to lower right. The image is watermarked “Artist’s concept” and “Credit: NASA/JPL-Caltech.”

TLDR

Brown dwarfs drift without a host star and are heated from within, NASA says. Its SPHEREx telescope studied 37 of them, revealing atmospheres containing water, carbon dioxide, carbon monoxide and methane.
