Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is ...

For years, computer simulations of the earliest galaxies have struggled to match what telescopes actually show. Depending on ...

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

Published in Monthly Notices of the Royal Astronomical Society, this breakthrough project, known as COLIBRE, offers a highly ...

Astronomers may have found the universe’s missing matter as diffuse hydrogen gas, revealed through subtle distortions in the ...

Galaxies created in the lab offer a view into what they looked like during formation and also how they might sound. This ...

Gravity has been tested extremely well inside the solar system. On cosmic scales, direct tests are harder. This study pushes ...

A groundbreaking study has finally quantified the kinetic energy of a black hole’s relativistic jets, and TL:DR, they're far more powerful than previously theorized.
