A star wiggling oddly around in space may be the signpost to one of the most sought-after objects in the galaxy. Some 5,825 light-years from Earth, a red giant star has been spotted moving as though in a slow orbital dance with a binary companion.

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.

Researchers in China have uncovered a low-mass black hole within the elusive mass-gap, defying previous scientific consensus. By combining radial velocity and astrometry, they identified this black hole in a wide binary system,

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,

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 energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end

The new jet, announced in the journal Nature, has been dubbed “Porphyrion” (a giant in Greek mythology) by its discoverers at the California Institute of Technology in the United States. It dwarfs NGC2663’s jet in actual size and is over 20 times larger – a true colossus.
