Three giant black holes discovered in a galaxy from the dawn of time

Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and are expected to eventually merge, while a third lurks farther away. One weighs an astonishing 80 million suns, and another is growing faster than conventional theories predict.

Two monster black holes could collide in just 100 years

Astronomers have uncovered compelling evidence of two supermassive black holes spiraling toward a potentially spectacular collision at the center of galaxy Mrk 501. A previously unseen jet of particles revealed the likely presence of a second black hole, with observations suggesting the pair completes an orbit every 121 days. Depending on their masses, these cosmic giants could merge in as little as 100 years.

Black holes of every size follow the same surprising rule

Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops to about 2% of the Eddington limit. That same threshold is known to trigger jets from much smaller black holes in the Milky Way.
