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.
From the far reaches of the observable Universe, astronomers have just seen a supermassive black hole suddenly flare to life.
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that can affect the surroundings of black holes.
A UK team of astronomers found an ultramassive black hole, an object over 30 billion times the mass of our Sun, in the foreground galaxy – a scale rarely seen by astronomers.
A comma-shaped molecular cloud near the center of the Milky Way seems to be orbiting one of the most sought-after objects in astronomy - an intermediate black hole.
Observations of supermassive black holes at the centres of galaxies point to a likely source of dark energy - the "missing" 70% of the Universe.
A team of scientists from the University in Bulgaria say they have developed a novel new method that could help scientists differentiate between black holes and hypothetical wormholes.
Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB). Its cause is unknown.
This discovery implies that there ought to be many dormant black holes spread across the Milky Way galaxy, the home of Earth.
