The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy,

The largest-ever pair of radiation jets has been discovered bursting out of a distant supermassive black hole, burning brighter than 100 galaxies, or over a trillion stars. From the end of one jet to the end of the other,

Two mighty beams of energy have been detected shooting in opposite directions from a supermassive black hole inside a distant galaxy - the largest such jets ever spotted, extending about 140 times the diameter of our vast Milky Way galaxy.

The largest-ever black hole jets ever seen hint that these cosmic monsters may play an even more significant role in shaping galaxies than previously thought.

Black holes are on a continuum of ultradense objects that form from the remnant cores of dead stars after they run out of fuel and collapse under gravity. White dwarfs form from stars up to about eight times the mass of the Sun, and have an upper mass limit of about 1.4 times the Sun's mass.

That is equivalent to lining up 140 Milky Way galaxies back-to-back. Credit: E. Wernquist / D. Nelson (IllustrisTNG Collaboration) / M. Oei

Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy. Black holes eat most space debris that falls their way.

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar stream that stretches out across 30,

Black holes hold some of the universe’s greatest mysteries, with giant empty spots in space sucking in whatever enters their gravitational pull. However, the mystery is now growing as astronomers are now saying there could be a swarm of black holes moving across the Milky Way.
