Astronomers have detected what appear to be bands of clouds streaking across the surface of a cool star-like body known as a brown dwarf.

Not quite planets and not quite stars, brown dwarfs are cosmic in-betweeners. Learning about their atmospheres could help us understand giant planets around other stars.

Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.

Brown dwarfs fill the "gap" between stars and the much smaller planets - two very different types of astronomical objects.

Brown dwarfs muddy a clear distinction between stars and planets, throwing established understanding of those bodies, and theories of their formation, into question.

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two epochs of high-resolution imaging of the combined source-lens baseline object.

In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object.

Cool brown dwarfs are a hot topic in astronomy right now. Smaller than stars and bigger than giant planets, they hold promise for helping us understand both stellar evolution and planet formation.

Brown dwarfs are sometimes called failed stars. They're stars' dim, low-mass siblings and they fade in brightness over time.

Astronomers have discovered what appears to be a tiny star with a giant, cloudy storm, using data from NASA's Spitzer and Kepler space telescopes.

Brown dwarfs are relatively cool, dim objects that are difficult to detect and hard to classify.

Astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered jets of material ejected by still-forming young brown dwarfs.

The Strange Case of the Missing Brown Dwarf

The new SPHERE instrument on ESO's Very Large Telescope has been used to search for a brown dwarf expected to be orbiting the unusual double star V471 Tauri.

Orbiting the Earth 353 miles above the ground, the Hubble Space Telescope silently pivots toward its new target. At the same time, flying 93 million miles away in interplanetary space, NASA's Spitzer Space Telescope receives commands to point itself at the same celestial target.
