This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked. This quasar is the most distant yet found and is seen as it was just 770 million years after the Big Bang. This object is by far the brightest object yet discovered in the early Universe.

Astronomers Can’t Explain How These Trillion-Degree Quasars Got So Hot

Astrophysicists have spotted a faraway object that’s hotter than any contemporary theory can explain, a discovery that might require scientists rewriting galaxy operation manuals for years to come. The first fruits of these mind-boggling observations were just published by an international group of scientists led by the Russian astrophysicist Yuri Kovalev in the journal Astrophysical Read More
