A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already ...

For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are ...

Smaller black holes can meet and merge in the wake of supermassive black holes. This may be because of the turbulence created by overlapping accretion disks and torque effects. Supermassive black ...

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

But black holes aren't too limited by size or number. On average, a standard black hole is about three to ten times the size of our sun. As massive as "regular" black holes can get, supermassive ...

Unprecedented cosmic dance : Dual black hole pairs. NASA's Chandra X-ray Observatory has captured extraordinary images of two dwarf galaxies, Mirabilis and Elstir & Vinteuil, located 760 million ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. Fan Zou is a ...

Scientists have discovered a pair of supermassive black holes that are doomed to merge into one enormous singularity. The findings could help astronomers understand what will happen when our own ...

Astronomers confirm ‘lite intermediate’ black holes, too large for ordinary stars, revealing clues about early stellar ...

When black holes collide into each other, they produce gravitational waves, as scientists learned in 2015 after recording a pair of stellar-mass black holes colliding for the first time.

A new model could provide scientists with a better idea how gravitational waves, or ripples, created by colliding black holes affect the very fabric of space-time.
