A bridge of stars connects two dwarf galaxies

The Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years, according to an international team of astronomers.

A black hole feeding frenzy that breaks records

A giant black hole ripped apart a nearby star and then continued to feed off its remains for close to a decade, according to new research. This black hole meal is more than 10 times longer than any other previous episode of a star's death.

Tail of stray black hole hiding in the Milky Way

By analyzing the gas motion of an extraordinarily fast-moving cosmic cloud in a corner of the Milky Way, astronomers found hints of a wandering black hole hidden in the cloud. This result marks the beginning of the search for quiet black holes; millions of such objects are expected to be floating in the Milky Way although only dozens have been found to date.

Tracing the cosmic web with star-forming galaxies in the distant universe

A research group has revealed a picture of the increasing fraction of massive star-forming galaxies in the distant universe. Massive star-forming galaxies in the distant universe, about 5 billion years ago, trace large-scale structure in the universe. In the nearby universe, about 3 billion years ago, massive star-forming galaxies are not apparent.

Our galaxy's black hole is spewing out planet-size 'spitballs'

If a star wanders too close to the black hole at the center of the Milky Way, the black hole's powerful gravity rips the star apart, sending a long streamer of gas whipping outward. New research shows that not only can the gas gather itself into planet-size objects, but those objects then are flung throughout the galaxy in a game of cosmic 'spitball'.

Hubble captures 'shadow play' caused by possible planet

Searching for planets around other stars is a tricky business. They're so small and faint that it's hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star.
