A pair of distant cosmic black hole mergers, measured just one month apart in late 2024, is improving how scientists understand the nature and evolution of the most violent deep-space collisions in ...

A radio image of two black holes orbiting each other in Quasar OJ287. The light comes from the glowing gas surrounding the black holes and the particle jets being emitted. Valtonen, Mauri et al., The ...

When scientists discovered an enormous black hole thousands of light-years from where it ought to be in space, they knew they had a cosmic oddity on their hands. NASA's Hubble Space Telescope showed a ...

Scientists imaged the heart of the OJ 287 galaxy, uncovering a curved plasma jet around what appears to be two merging supermassive black holes. The structure reveals unimaginable energy levels and ...

When galaxies collide, it's not a gentle affair, but it does take millions of years. Over this time, the two massive star systems slowly merge together, their gravitational pull drawing them closer.

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

Astronomers had long suspected that certain quasars—those brilliant, otherworldly light sources fueled by supermassive black holes—could harbor two black holes rather than one. That theory, long ...

After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287. Astronomers have captured a radio image showing two black ...
