A galaxy some 750 million light-years away has been discovered hosting the heftiest pair of supermassive black holes we've ever seen.
The beginning of the Universe has always been something of a chicken-and-egg problem. Did stars and galaxies form first, with black holes slowly coalescing in their midst? Or did black holes appear before the first galaxies?
Certainly, we could tap into all the heat and kinetic energy of a black hole's accretion disk and jets, but even if all you had was a black hole in empty space, you could still extract energy from a trick known as the Penrose process.
A small black hole is helping scientists understand how mysterious cosmic rays can barrel through the Universe and hit Earth at nearly the speed of light.
An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
Astronomers using the James Webb Space Telescope (JWST) have detected the earliest known black hole. Located more than 13 billion light-years away, it dates to a mere 400 million years after the Big Bang.
In a magnificent first, we finally have direct observational evidence of the stellar process that produces neutron stars and black holes.
India has recently launched its first satellite to study black holes as it seeks to deepen its space exploration efforts ahead of an ambitious crewed mission next year.
The burst that originated some 2.4 billion light-years away from Earth and struck the planet on 9 October last year may have led to changes in the upper ionosphere, according to a new study.
Every 76 minutes, like clockwork, the gamma-ray flux of Sagittarius A*, the supermassive black hole in our galaxy, fluctuates, suggesting an orbital motion of something whirling madly around the black hole.
Two NASA space telescopes teamed up to scrutinize a distant galaxy and discovered something mind-boggling: a gargantuan black hole inside a galaxy that’s more than 13 billion years old.
The closest black hole to Earth was thought to be 1,560 light-years away - but a new study suggests there could be one around 150 light-years away.
According to a new analysis of a type of galaxy known as a blazar, the best explanation for unusual changes in their glow is a pair of supermassive black holes locked in a decaying orbit.
U.S. astrophysicists has found via simulations that some black holes might be traveling through space at nearly one-tenth the speed of light.
Scientists have detected an active supermassive black estimated to have been created 570 million years after the Big Bang.
