It is situated near a supermassive black hole that weighs about 20 billion times more than our Sun. The quasar, APM 08279+5255, emits an extraordinary amount of energy—equivalent to that ...

They found a type of ultra-powerful galaxy that gobbles up everything around it. Its energy is so intense that, if it were ...

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 ...

Astronomically speaking, the quasar, which weighs 450 million times the mass of our sun, is considered to be smaller than typical quasars, which can reach masses that are billions of times heavier ...

The triple star system is sending comets, asteroids and meteors our way, and the number of interstellar objects entering the solar system will rise.

The giant jet flips the script on the origins of these structures, which were once thought to be linked only to extremely large black holes.

The J1601+3102 quasar is also of modest size, just 450 million times more massive than the sun. Quasars are sometimes known to tip scales at billions of times heavier than the sun. "Interestingly ...
