Black hole

The possible Saturn-sized planet was detected in the galaxy Messier 51, 28 million light-years from Earth, making it the most distant exoplanet ever found.

The last ever explosions will be silent fireworks that take place long after everything else in the universe has died, a study has found.

One suggestion is the star collapsed into a black hole without producing a supernova—a phenomenon that has never been identified in such a large star before.

The black hole forms part of a triple star system known as HR 6819, which can be seen without binoculars or telescopes from the southern hemisphere on a dark, clear night.

"It's not just a rare chance event. There has to be a mechanism to form them," study author Anna Ciurlo told "Newsweek."

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

Researchers have observed the faint glow of "gas halos" around galaxies hosting supermassive black holes.

Researchers in China found a star 15,000 light years away orbiting a "dark companion" that defies theories of stellar evolution.

This has not stopped physicists attempting to work out how you would spot one if they did—because while there is no proof they do exist, they are at least theoretically possible.

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."

Scientists spotted the X-ray flash using NASA's NuSTAR satellite.

Scientists are now trying to work out what caused the mystery burst .

Japanese researchers propose new plan to hunt down our galaxy's "isolated black holes."

Without female STEM role models, we risk acquiescing to a world where even brilliant minds like Bouman are dragged into discriminatory devolutions.

"This is one of the most extraordinary black hole systems I've ever come across," James Miller-Jones said.

Bouman, a computer scientist with the Event Horizon Telescope project, talks about seeing the first-ever image of a black hole.

"Space Hobbits are our new frontier."

Scientists with the Event Horizon Telescope project unveiled the image at news conferences across the globe.

In 2017 scientists created an Earth-sized virtual telescope and used it to take a "picture" of a black hole.

On June 16, 201, the discovery of a strange flare in the sky was reported in an astronomical telegram.

The observations offer "a resounding confirmation" of the supermassive black hole long-believed to be lurking at the heart of our galaxy.

The supernova may indicate the birth of a neutron star binary system, according to a new paper.

If correct, the new theory would mean these black holes would all have about the same mass.

"The reality is that global economic growth is closely linked to trade, and raising tariffs will inevitably reduce the volume of trade and drive down business confidence," the article argued.

The incredible discovery will help astronomers unlock the secrets of the universe's very first galaxies.

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

The broadcast will "create a link" between Hawking's presence on Earth, his desire to visit space and his scientific explorations of the universe, his daughter said.

Last year's collision was the first in which scientists could actually see what was happening during and after the collision.

The behemoth gobbles up the equivalent of our sun's mass every two days.

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