Dyson spheres encompassing around black holes could yield up to one million times more energy than those built around stars, according to a new study.
The detection confirms a key prediction of Einstein's theory of general relativity.
Ziri Younsi, a member of the Event Horizon Telescope collaboration, explains how scientists managed to photograph a black hole across 55 million light years.
MIT astrophysicist Nergis Mavalvala talks about the discovery of gravitational waves—and everything that has followed—on Motherboard’s “Space Show.”
Palomar 5, a cluster flanked with giant star tails, will be completely usurped by black holes in one billion years, scientists predict.
A wave signal from space validates Hawking’s prediction that the area of an event horizon should never decrease.
Nobody had ever seen a system containing a neutron star and a black hole. In January 2020, scientists detected two of them.
Nobody knows what causes quasi-periodic eruptions (QPEs), but a new study has found a much more efficient way of detecting these mysterious explosions.
Located 1,500 light years away, the 'Unicorn' is the closest known black hole and is also unusually small.
Ripples in spacetime caused by black holes colliding in darkness could help scientists clock the expansion of the universe.
If confirmed, the collision between never-before-seen boson stars may solve the long search for the source of dark matter.
The active galactic nucleus is powered by a supermassive black hole and was spotted just 670 million years after the Big Bang, making it the most distant quasar ever discovered.
