First weather map of brown dwarf

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.

This black hole is having a light snack

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.

The stormy atmosphere of a brown dwarf

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.

'Very little' telescope discovers weird new planets

Using a lens no more powerful than the one on your digital camera, astronomers have discovered two unusual exoplanets.

Tiny brown dwarf found floating free in space

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 observe biggest storm ever seen

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.

Cool brown dwarf could have water-based clouds

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.

Hubble discovers mystery object orbiting brown dwarf

Astronomers have discovered a planet-like object circling a brown dwarf that appears to have formed much more quickly than was previously thought possible.
