Ultramassive black holes: how does the universe produce objects so massive?
Black holes are the most massive objects that we know of in the Universe.
Not stellar mass black holes, not supermassive black holes (SMBHs,) but...
New discovery sheds light on very early supermassive black holes
Astronomers from the University of Texas and the University of Arizona have discovered a rapidly growing black hole in one of the most extreme...
Scientists find link between black holes and dark energy
Researchers have uncovered the first evidence of “cosmological coupling”—a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.
Scientists detect a tadpole playing around black hole
A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects.
This...
Without more data, a black hole’s origins can be spun in any direction
Researchers say that current results depend on models rather than data.
Clues to a black hole's origins can be found in the way it spins,...

Astronomers have discovered a galactic table for two — a pair of unusually close black holes that are feeding together after their respective galaxies...
Millions of fake universes clarify how black holes grow
Black holes are surrounded by a mysterious, invisible layer—the event horizon—from which nothing can escape, be it matter, light, or information.
The event horizon swallows...
Machine learning reveals how black holes grow
As different as they may seem, black holes and Las Vegas have one thing in common:
What happens there stays there – much to the...
A black hole has been burping for 100 million years
Black holes are gluttonous behemoths that lurk in the center of galaxies.
