Caption This deep image shows the nebula (cyan) extending across 2 million light-years that was discovered around the bright quasar UM287 (at the center of the image). The energetic radiation of ...

The black hole’s mass is over half that of all the stars in the surrounding galaxy, a record for any galaxy hosting a quasar.

A new image released by the European Space Agency shows the powerful telescope's latest — and decidedly glamorous — finding: ...

A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of ...

Gravitationally lensed quasar: This picture shows a quasar that has been gravitationally lensed by a galaxy in the foreground ...

"It's difficult to explain how these quasars could have grown so big if they appear to have nothing to feed from." ...

Using the James Webb Space Telescope (JWST), astronomers have spotted the earliest powerful "galaxy-size" wind blowing from a feeding supermassive black hole-powered quasar. The powerful wind is ...

Astronomers have identified the brightest object ever observed in the universe, a quasar named J0529-4351. This quasar is 500 trillion times brighter than the Sun, setting a new record for ...

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 ...

(In fact, "a quasar’s light outshines that of all the stars in its host galaxy combined," NASA explains.) An isolated quasar in deep space, circled in red. Credit: Christina Eilers / EIGER team ...
