It isn't just supermassive black holes that are messy eaters. Using a Japanese space telescope called XRISM, scientists have found that small black holes are a "hot mess," too.
This quiz invites you to journey into the depths of these gravitational giants.
Astronomers just ruled out merging black holes as a possible solution to a giant discrepancy plaguing cosmology.
Unexpected X-ray polarization challenges long-held ideas about how black holes behave.
There's a gap in black hole masses, and experts believe here is where 'lite intermediate black holes' reside.
A newfound supermassive black hole from the dawn of the universe challenges how early cosmic giants formed.
Scientists have tapped into gravitational lensing and stellar dynamics to confirm the existence of a black hole with 36 billion solar masses.
A bold new proposal envisions launching laser-propelled nanocraft to a nearby black hole to test Albert Einstein's theory of general relativity.
A beam of particles speeding away from a monstrous black hole is severely kinked, suggesting that the black hole is actually part of the most extreme binary system known.
New research suggests that primordial black holes could have played an important role in the formation of the universe's first stars, but did they help or hinder?
