Massive, invisible stars that formed in the earliest days of the Universe may hold clues to the true nature of dark matter.

For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

A groundbreaking study has finally quantified the kinetic energy of a black hole’s relativistic jets, and TL:DR, they're far more powerful than previously theorized.

A black hole roughly 7,000 light-years from Earth is firing a jet of superheated plasma at close to half the speed of light, ...
