In the vicinity of black holes, space is so warped that even light rays may curve around them several times visualizing multiple versions.

As astronomers look out at the distant cosmos, it’s only natural that they would also look inward, to the center of our own Milky Way.

Astronomers have been able to identify the widest range of elements in a relatively bright star beyond our solar system yet.

Above the atmosphere is space. It’s called that because it has far fewer molecules, with lots of empty space between them.

Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time.

The larger the mirror, the more light is collected. This means that we can see farther back in time to observe star and galaxy formation.

An international team of astronomers has spotted the most distant astronomical object ever: a galaxy some 13.5 billion light-years away.

Have you ever wondered what it would be like to travel to outer space – and then keep going? What would you find?

Astronomers identified a number of stellar streams from past mergers years ago, and also used globular clusters to construct a timeline.

Our galaxy is a giant ‘smoothie’ of blended stars and gas but a new study tells us where the components came from.

When tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter which we can’t see.

Have you ever wondered what it would be like to travel to outer space – and then keep going? What would you find?

The galaxy, dubbed Alcyoneus, is a large radio galaxy that spans 16.3 million light-years or roughly 150x the span of the Milky Way galaxy.

A team of German astronomers have discovered a strange new type of star covered in the by-product of helium burning.

A new study suggests the existence of a direct interaction between the elementary particles that make up the dark matter and ordinary matter

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way’s dwarf satellite galaxies, called Leo I.

Studying the atmospheres of white dwarfs that have been “polluted” by such debris, researchers have identified exotic rock types.

If the known laws of physics hold, then a galaxy-spanning human civilization is impossible. Unless of course you can build a warp drive.

Astronomers have reported the discovery of a structure thought to be a "protocluster" of galaxies 11 billion light-years from Earth.

A planet transiting a star outside of the Milky Way galaxy may have been detected for the first time by the Chandra X-ray Observatory.
