An illustration of a quasar, powered by an accretion disk of gas and dust swirling into a central supermassive black hole.

Quasars are some of the brightest objects in the universe. A quasar is powered by large amounts of matter falling into the supermassive black hole at the center of a galaxy. Collisions and mergers ...

An illustration of the quasar P172+18 as it blasts out powerful jets of matter and radiation. Scientists may have solved a 60-year-old mystery by discovering that quasars — energetic objects that are ...

We don’t understand quasars all that well, but are pretty certain that these incredibly bright lights belong in the centers of galaxies. So it looked a little weird when astronomers spotted quasar 3C ...

In April 2023, astronomers announced they had discovered a partnership between two closely bound quasars, representing a merger between galaxies just 3 billion years after the Big Bang. The first ...

You'll need more than sunglasses to look at this shiny object in the sky. The brightest object in the universe has been discovered, a quasar from when the universe was just 7 percent of its current ...

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made an image revealing tantalizing details of a quasar nearly 13 billion light-years from Earth -- an object ...

A cluster of eleven quasars on a galactic boundary challenges existing models, prompting a rethink of quasar formation in large-scale cosmic structures. (Nanowerk News) A newly discovered cluster of ...

The densest cluster of supermassive black holes identified in the Universe. The background image was taken by Hyper Suprime-Cam on the Subaru Telescope. The red and blue shadows represent the density ...
