Mergers with other galaxies may have knocked the black hole in dwarf galaxies off-center, creating "wandering" black holes.

Intriguingly, the Neptune-like planet is is about four times bigger than the star itself.

"Up until now, such a concentration of three supermassive black holes had never been discovered in the universe," Peter Weilbacher, from the Leibniz Institute for Astrophysics Potsdam, said.

The center of our galaxy is located around 26,500 light-years away from Earth.

The latest findings could have important implications for our understanding of how massive stars form.

Researchers estimate that the explosion lasted for approximately 300,000 years.

Astronomers have cast new light on a huge, empty expanse of space that surrounds our galaxy known as the Local Void.

The black hole is located at the center of the spiral galaxy NGC 3147 around 130 million light-years away from Earth.

The findings expand our knowledge of black holes and the galaxies within which they are often found.

Messier 90 belongs to a vast collection of more than 1,200 galaxies known as the Virgo Cluster, which has a diameter of 15 million light-years.

"We usually think of spiral galaxies as being quite flat."

Scientists think that at the heart of nearly every galaxy lies a supermassive black hole (SMBH) with immense gravity.

Our galaxy has "died" once before and we are now in its second life, according to a new hypothesis.

The image features around 15,000 galaxies, the oldest of which dates back to 11 billion years ago.

The galaxy belongs to a recently discovered, rare and unusual class of stellar systems known as ultracompact dwarfs.

From jaw-dropping pictures of interlacing galaxies to man's first steps outside of Earth, these are NASA's most incredible images so far.

The study has proved the theory holds beyond the Milky Way.

They were created using data from nearly 1.7 billion stars.

Widening waistbands are truly universal.

Competing winds from black holes and stars wrestle to give this galaxy its strange butterfly shape.

The discs contain gas, dust and even young planets that are still in the process of forming as the building blocks of planetary systems.

The pictures have helped researchers to identify an elusive object, known as an isolated neutron star, outside our own galaxy for the first time.

The galaxies were around in the early stages of the universe, 13 billion years ago.

Scientists think the galaxy is expanding at about 550 yards per second.

Scientists think the star was once part of a binary system until its companion exploded in a powerful supernova, causing it to be blasted off into space.

Lying some 63 million light-years from the Milky Way, the elliptical galaxy NGC1052-DF2 seems to be completely made up of normal matter.

The Messier Catalog contains some of the most magnificent and beautiful sights in the Northern Hemisphere sky.

"It's not Swiss watch precision," researchers say.

The galaxy, known as NGC 1277, is located 240 million light-years from Earth.

The fireworks are taking place about 350 million light-years away.
