Astronomers Find Jupiter-like Cloud Bands on Closest Brown Dwarf

Brown dwarfs, often called “failed stars,” weigh up to 80 times as much as Jupiter, yet their gravity compacts them to about the size of Jupiter in diameter.

In contrast its companion brown dwarf, Luhman 16B, shows signs of patchy clouds.
