Did the first black holes appear before galaxies? Astronomers think black holes are missing link in early universe evolution

February 7, 2024

Black holes may be less cosmic villains and more like co-creators in the early universe.

Astronomers have discovered two pairs of quasars in the distant Universe, about 10 billion light-years from Earth. In each pair, the two quasars are separated by only about 10,000 light-years, making them closer together than any other double quasars found so far away. The proximity of the quasars in each pair suggests that they are located within two merging galaxies. Quasars are the intensely bright cores of distant galaxies, powered by the feeding frenzies of supermassive black holes. One of the distant double quasars is depicted in this illustration.

Double trouble! Astronomers discover distant quasar pairs

A pair of quasars closer together than any others previously observed could help researchers understand supermassive black hole binaries.

The discovery of primordial black holes could answer a multitude of lingering questions such as the nature of dark matter, ...

With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole, the first time such a close grouping has been seen within the first billion years of the Universe. This artist’s impression shows the central black hole and the galaxies trapped in its gas web. The black hole, which together with the disc around it is known as quasar SDSS J103027.09+052455.0, shines brightly as it engulfs matter around it. (ESO/L. Calçada)
