ESO's Very Large Telescope has been used to create the first ever map of the weather on the surface of the nearest brown dwarf to Earth. An international team has made a chart of the dark and light features on WISE J104915.57-531906.1B, which is informally known as Luhman 16B and is one of two recently discovered brown dwarfs forming a pair only six light-years from the Sun.
Astronomers are observing a black hole that woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close.
Astronomers using NASA's Spitzer and Hubble space telescopes have managed to probe the stormy atmosphere of a brown dwarf, creating the most detailed "weather map" yet for this class of cool, star-like orbs.
Using a lens no more powerful than the one on your digital camera, astronomers have discovered two unusual exoplanets.
Astronomers have found a 'failed star', or brown dwarf, only six times the size of Jupiter, along with two dozen others that float free in space.
Astronomers say they've observed extreme brightness changes on a nearby brown dwarf that could indicate a storm more dramatic than any ever before seen on a planet.
We normally think of stars as hot - but scientists using ESO's Very large telescope say they've found a pair of cool brown dwarfs, one of which is no hotter than a sauna or a cup of tea.
Astronomers have discovered a planet-like object circling a brown dwarf that appears to have formed much more quickly than was previously thought possible.
