The researchers propose that this ejection resulted from the collision of two galaxies, causing their central black holes to ...

Astronomers have made an extraordinary discovery—the largest and most distant water reservoir ever detected in the universe.

These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave background. The ancient radiation, the earliest fossil of light from 380,000 years ...

Scientists reclassified PBC J2333.9-2343 as a blazar after its jet shifted toward Earth. Discover why this black hole is ...

Scientists added, however, that the black hole fueling the quasar producing the jets is small compared to other black holes, equaling 450 million suns. The discovery was made by the Gemini North ...

The image shows the galaxy NGC 4438, where a supermassive black hole is releasing huge bubbles of hot gas into space. The image captures an elliptical galaxy surrounded by a dark dust lane, seen ...

Funneling all that material causes some black holes to unleash an extraordinary amount of energy that scientists believe fuel the formation of a quasar — the brightest known objects in the universe.

Astronomers have discovered an enormous radio jet from the early universe, extending over 200,000 light-years and powered by a supermassive black hole ...

Flickers and Flares: Milky Way's Central Black Hole Constantly Bubbles With Light ... have detected an intensely brightening and dimming quasar that may help explain how some objects in the ...
