Astronomers detected rare and never-before-seen structures in the galaxy's magnetic field including a helix-shaped featured and two vast "superbubbles."

"This all-sky image completely changes the way we look at the energetic universe," said researcher Peter Predehl.

"The flash was so powerful that it lit up the stream like a Christmas tree," said researcher Andrew Fox.

Superflares are explosions up to 10,000 times more energetic than the typical solar flares that our sun produces.

"While we have long been able to directly probe the winds of the bodies in our own solar system, we've had to conjecture what they're like in other kinds of bodies," researcher Peter Williams said.

NGC 4651 is sometimes referred to as the "Umbrella Galaxy" due to a faint umbrella-shaped structure that surrounds it.

Observations from NASA's Hubble telescope show these outflows contain, on average, 10 times more energy than previously thought.

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.
