Using the ESA's Euclid space telescope, astronomers have discovered a treasure trove of black hole-powered quasars in the ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of a quasar, powered by an accretion disk of gas and dust swirling into a central supermassive black hole.

The quasars date back to a time when the universe was only 670 million years old.

Euclid telescope doubles early quasar finds, resets record for oldest Early-universe beacons reveal how supermassive black ...

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 ...

Astronomers observed ancient quasars that appear to be surprisingly alone in the early universe. The findings challenge physicists' understanding of how such luminous objects could have formed so ...

The hearts of some galaxies glow so brightly that they are given a special name: Quasars. Powered by supermassive black holes at the center of these galaxies, these regions give off tremendous amounts ...

A new Northwestern University-led study is changing the way astrophysicists understand the eating habits of supermassive black holes. While previous researchers have hypothesized that black holes eat ...

A Yale-led team of astronomers has detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery, ...

Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA’s Spitzer and Hubble space telescopes.

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...
