The two black holes lie just 1,560 and 3,800 light-years from our planet, respectively.

There's nothing to worry about. It's dormant and it won't eat us.

Gaia BH1 has a mass of 9.62 times the mass of the Sun and is orbited by a bright Sun-like star at about the same distance as our planet orbits the Sun.

Black holes are the most extreme objects in the universe. Supermassive versions of these unimaginably dense objects likely reside at the centers of all large galaxies. Stellar-mass black holes—which weigh approximately five to 100 times the mass of the sun—are much more common, with an estimated 100 million in the Milky Way alone.

The dormant stellar-mass black hole in the Large Magellanic Cloud is the first to be confirmed outside of the Milky Way.

A team of astrophysicists known for debunking previous supposed black holes announced a discovery of their own on Monday: the first "dormant" stellar-mass black hole spotted orbiting a star in a nearby galaxy.

A server at a California Fleming's Prime Steakhouse & Wine Bar is being sued for racial discrimination by a Black patron, the La Jolla Light reports. The suit alleges that plaintiffs Mychel McKillian, who is Black, and Denise Grimaldo, who is Hispanic, were dining with others at the San Diego-area r...

The mass of the supermassive black hole in the center of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, is about 600,000 solar masses.

Star system observed 8,000 light-years away may be the first direct evidence of "gentle" black hole formation.

A surprising discovery about the black hole V404 Cygnus is expanding our understanding of black holes, the objects they can host, and the way they form.

Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example, are often found orbiting each other. One pairing that has proven to be quite rare is that between a sun-like star and a type of dead star called a neutron star.

For many years, binary star research has been as neglected as an old Tamagotchi. But now, the Gaia space telescope is leading a resurgence in interest in...

One of them is barely a star at all, and together the pair could fit inside the girth of our Sun.

Researchers have spotted the fastest runaway star to have ever escaped the Milky Way as a result of a massive thermonuclear explosion.

Until recently, there were only ten known stars on trajectories that will allow them to escape the Milky Way galaxy, thrown astray by powerful supernova explosions. A new study using data from ESA's Gaia survey this June has revealed an additional six runaways, two of which break the record for the fastest radial velocity of any runaway star ever seen: 1,694 km/s and 2,285 km/s.

This black hole is ten times as massive as the sun and is 1,600 light years away—three times closer than the previous record holder.

A team of international experts, renowned for debunking several black hole discoveries, have found a stellar-mass black hole in the Large Magellanic Cloud, a neighbor galaxy to our own. The researchers found that the star that gave rise to the black hole vanished without any sign of a powerful explosion.

'Put a black hole where the Sun is...and you get this system,'

Discovery could help astronomers estimate a population of hidden black holes
