Astronomers use “solar mass” as the basic unit of measurement for a black hole’s mass. One solar mass is equal to the mass of the sun, about the mass of 333,000 Earths (or 1.989 x 10^30 ...

Scientists have observed a new type of black hole that is too heavy to have been born from a star but still too slim to … The ...

The researchers found that the large majority of this mass, around 99.9% of it, was due to the black hole. We can now be confident that Sagittarius A*’s mass is around 4.3 million times the mass ...

The big surprise is that the black hole mass for NGC 1277 amounts to 14% of the total galaxy mass, instead of usual values around 0,1%. This beats the old record by more than a factor 10.

Astronomers have made another significant breakthrough in the arena of black hole exploration. A team of experts believes they have detected what appears to be one of the heaviest black holes ...

There are three categories of black holes. The smallest, like 'the Unicorn,' are so-called stellar mass black holes formed by the gravitational collapse of a single star.

This diagram shows how the diamater of the 17-billion-solar-mass black hole in the heart of galaxy NGC 1277 compares with the orbit of Neptune around the Sun. The black hole is eleven times wider than ...

The monster black hole in galaxy cluster Abell 85 is roughly the size of our solar system, but packs the mass of 40 billion suns. Skip to content Introducing the all-new Astronomy.com Forum!

Our galaxy's central black hole is about 4 million times the mass of our sun, which is in the normal range for most galaxies. NGC 1277 has a black hole that's 17 billion solar masses—more than ...

"It is significant that this intermediate mass black hole was found only 20 light-years from the supermassive black hole at the galactic center," says Tomoharu Oka, co-lead author of the study.

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. ... Another intermediate-mass black hole discovered at the center of our galaxy Date: July 18, 2024 ...

With a mass 17 billion times that of the Sun, the newly discovered black hole in the center of the disk galaxy NGC 1277 might even be the biggest known black hole of all.
