V4641 Sagittarii is a system about 20,000 light-years from Earth. Astronomers have now detected photons from V4641 Sagittarii carrying energies of up to a staggering 200 teraelectronvolts (TeV).
In this system, called V404 Cygni, the black hole is consuming a small star that is spiraling in very close and fast while a newfound third star circles the black hole from much farther away.
A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.
Researchers at MIT suggest that the microscopic "primordial black holes" could be blasting through our solar system at least once a decade.
The latest discovery used the Hubble Space Telescope (HST) to spot three bright, visible light 'hot spots' deep inside a pair of colliding galaxies.
Although our Universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk - walking on the edge of a very dangerous cliff.
Dark matter could provide supermassive black holes the brakes they need to bring them crashing together at the end of a long, spiraling journey towards their destiny.
Astronomers have found evidence for an intermediate-mass black hole in IRS 13, a population of dusty stellar objects within the nuclear star cluster of our Milky Way Galaxy.
An international team of astronomers has detected seven fast-moving stars in Omega Centauri region. These stars provide compelling new evidence for the presence of an intermediate-mass black hole.
A black hole discovered lurking in the Cosmic Dawn is just way too big to easily explain.
In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories.
Astronomers discovered the first pair of merging quasars from the Cosmic Dawn, 900 million years after the Big Bang.
New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars.
The researchers say that these black holes mergers are a window into Hawking Radiation. When black holes merge, they may create so-called "morsel" black holes the size of asteroids that are ejected into space.
It turns out that certain black holes act just like the terrifying sci-fi battle station, spinning around to fire giant beams at various targets in the cosmos.
