Observations by a system of radio telescopes have offered the first visual evidence for the existence of black hole pairs. But vital follow-up observations are needed before we know for sure.

Using the James Webb Space Telescope, astronomers discovered an extreme version of "little red dots" dubbed "The Cliff." Its light suggests that it could be a never-before-seen class of objects called a "black hole star."

For the first time, astronomers have directly measured a solar-system-size corona around a distant supermassive black hole, thanks to a rare cosmic alignment.

Researchers have combined 15 years' worth of radio data to peer through the cone of a high-energy jet and unravel the magnetic mysteries of a "blazar" billions of light-years from Earth. The new findings also shed light on the origin of elusive "ghost particles."

A beam of particles speeding away from a monstrous black hole is severely kinked, suggesting that the black hole is actually part of the most extreme binary system known.

NASA's Chandra X-ray Observatory has captured a striking image of a distant quasar from the "cosmic noon," including a giant energy jet "being illuminated by the leftover glow from the Big Bang itself."

Astronomers have used the James Webb Space Telescope (JWST) to revisit a misunderstood black hole thought to be gulping matter 40 times faster than the theoretical limit. It turns out, dust may have obscured the truth.

Astronomers have used a continent-sized radio telescope to find the largest black hole jet ever observed in the early universe.

A new JWST study has revealed the true origins of a luminous quasar that has been duplicated six times as its light "zig-zags" through space-time via a phenomenon first predicted by Albert Einstein. The unusual light show could help tackle one of cosmology's biggest problems, experts claim.

How did supermassive black holes get big so fast? Astrophysicist Souphie Koudmani tells us how she and her colleagues are finding out.
