The explosion occurred on the surface of a pulsar around 11,000 light-years away.

"I can't believe we are the only living entity in the universe," Didier Queloz said

Black holes are dead stars that, after exploding as supernovae, have so much mass that nothing can hold them together, causing them to collapse into a singularity.

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

Five years ago scientists proposed the hypothetical existence of a large world tens of millions of miles from the Sun, which has come to be known as "Planet Nine."

"Simulations and movies like these really help us visualize what Einstein meant when he said that gravity warps the fabric of space and time," the creator of the images said.

A team of astronomers has discovered the "fastest eclipsing white dwarf binary" star system in the known universe.

The observatory is expected to map around 100,000 galaxy clusters—the largest known gravitationally bound structures in the universe—and three million supermassive black holes.

Astronomers have measured the spin rate of five, distant supermassive black holes for a study published in the Astrophysical Journal.

The probe will use gravity like a slingshot on its seven-year voyage to Mercury.

The discovery could help unlock the secrets of the formation of the universe.

The latest findings shed new light on supernova explosions and the late stages of stellar evolution.

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

The jets could provide a link between neutron star mergers and gamma ray bursts—the brightest events ever observed.

Is a mysterious planet lurking at the edge of our solar system?

The searing hot ball of gas at the heart of our planetary neighborhood is home to almost all the mass of the solar system—but it's getting lighter all the time.

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

We might need new physics to know, and the result could be "a showstopping change of our picture of the cosmos."

Who is Georges Lemaître and what were his most important ideas?

The finding shines new light on our understanding of the cosmos.

This is the first time astronomers have directly imaged the brutal phenomenon.

If proven correct, the theory could revolutionize our understanding of the cosmos.

The event horizon is the point of no return beyond which nothing, not even light, can escape the immense gravitational pull of the black hole.

You can help astrophysicists keep track of unidentified supernovas in the universe, and be recognized as a co-discoverer.

Only a few such emissions have ever been observed.

In 2016, scientists from the California Institute of Technology found evidence to suggest that a planet larger than Earth could be hiding beyond the orbit of Pluto, out in the furthest reaches of the Solar System.

The era of big data is revolutionizing how astronomical discoveries are made.

The existence of multiple universes is hotly debated among scientists.

Our sun will die in about 10 billion years' time.

Scientists discovered large quantities of the foul gas in the cloud tops of the planet
