When one star took a fatal dive into another dying star, it set off an explosive reaction that created an object even colder than space itself.
How those black holes grew to their enormous sizes in less than one billion years after the Big Bang is a long-standing problem in astrophysics.
A study shows two black holes in space combining millions of light years away are growing to be multiple times the size of our sun.
Events on Earth like tornadoes and earthquakes are nothing compared to the dangers of our solar system, our galaxy and our universe.
Do Black Holes Really Have Event Horizons? Einstein’s General Theory Of Relativity Passes Another Test
Astronomers decided to put Einstein’s General Theory of Relativity to test with an experiment to verify one of the basic principles of black holes.
Supermassive Black Holes May Be Ruining Potentially Habitable Planets By Destroying Their Atmospheres
A study shows supermassive black holes may be making planets uninhabitable.
A star suffered an epic fail when it quietly collapsed into a black hole instead of exploding in a brilliant supernova.
The galaxies formed less than one billion years after the Big Bang and could explain the existence of massive galaxies in the early universe.
Called “naked singularities,” their existence has been predicted in a “saddle”-shaped universe. If proven, the new theory would undermine general relativity.
A new bright spot scientists just saw in a powerful galaxy might be a rare type of supernova explosion or it could be a supermassive black hole that just ate a delicious meal.
Black holes are notorious serial starkillers, so good at what they do that we don’t even have photos of them, just the NASA version of police sketches.
Astronomers may have found a supermassive black hole that has left its usual place at the center of its galaxy and is on the move.
Astronomers have discovered three quasars — each a billion times the mass of the sun — whose very existence challenges our conventional understanding of how supermassive black holes form and evolve.
Observations made using NASA's NuSTAR telescope have revealed that supermassive black holes in merging galaxies do most of their feeding during the later stages of galactic mergers, when they're heavily obscured.
When science and art come together, it can help us envision what our universe looks like beyond the bonds of Earth’s gravity.
A binary star exploded in a supernova and showered its only friend in calcium.
Astronomers say a pulsar, which is the lighthouse of stars, is orbiting a black hole in the constellation Sagittarius.
XB091D had slowed down to one revolution every few seconds, but began accelerating again less than one million years ago, and currently revolves once every 1.2 seconds.
Two supermassive black holes have been found at the middle of galaxies that are tiny because they were torn apart and eaten by others.
The baby stars forming in starburst galaxy NGC 4536 will die young because they are burning up their gas too quickly.
After five nights of observations, astronomers associated with the Event Horizon Telescope project said Wednesday that they may have succeeded in snapping a photograph of Milky Way's supermassive black hole.
Do Naked Singularities Exist? Quantum Effects May Be Shielding The Universe From Uncloaked Infinities
In a new theoretical study, a team of researchers state that quantum gravity would very quickly turn a naked singularity, even if it is created, into a black hole.
The observation campaign, from April 5-14, uses a number of telescopes from around the world to create one large “Event Horizon Telescope.”
A team of researchers has taken a significant step toward solving the longstanding mystery surrounding these complex and calamitous events.
Black Hole vs. Supernova: How These Things Could Kill You In Space, According To Neil deGrasse Tyson
A black hole would tear you to pieces and a supernova would vaporize you. Here’s how to die in space in style.
The ambitious international collaboration, which will begin observations this week, aims to photograph the shadow of the event horizon of the black hole at the centre of our galaxy.
A large disk galaxy and a small “dwarf” galaxy merged in a system called Was 49, and the smaller partner has been found with a much larger-than-expected supermassive black hole.
In the winds rushing away from a supermassive black hole are all the right ingredients for new stars to be born.
Weighing more than 1 billion suns and about 8 billion light-years away, the black hole was likely kicked out of its place by gravitational waves with energy equivalent to 100 million supernovas exploding simultaneously.
A new computer model has finally solved a longstanding cosmic quandary — how did supermassive black holes form in the first billion years of the universe?
