After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of ...

In the 1980s, Finnish astronomer Aimo Sillanpää noticed its repeating light pattern and proposed the idea of two black holes.

It was spotted in the spiral galaxy NGC 3627, around 31 million light-years from our solar system in the constellation Leo.

Quasars are extraordinarily bright regions surrounding supermassive black holes, where infalling gas and dust generate enormous energy.

For 50 years, astronomers have been searching for evidence of winds emanating from the black hole Sagittarius A*. Now, they ...

Astronomers have captured the first-ever image of two supermassive black holes orbiting each other in quasar OJ287, 5 billion ...

Gauging the mass of a black hole is tricky, but astronomers have devised multiple methods to measure the heft of these galactic gluttons ...

New fear unlocked: spontaneous black hole implosion. Fresh research predicts that planets may be able to accumulate enough dark matter to suddenly form a black hole at their core. As the intruder ...

Astronomers studying the supermassive black hole M87*, a behemoth six and a half billion times the mass of the Sun, have uncovered a new way these cosmic monsters unleash their power.

A plane flying near a black hole would first be pulled by immense gravity, then torn apart by tidal forces, and ultimately stretched into spaghetti.

"We're really pushing the boundaries of what current technology can detect." A team of astronomers says it has identified the most distant black hole ever confirmed — a cosmic heavyweight that formed ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.
