Can a massive star collapse into a black hole without first exploding in a supernova blast? That’s at least one explanation for the disappearance of a star 2.5 mil times brighter than the sun in a dwarf galaxy 75 mil light years away.
Researchers have observed a gamma-ray burst with an afterglow that featured the highest energy photons -- a trillion times more energetic than visible light - ever detected in a burst.
For the first time, astronomers have directly witnessed the aftermath of a black hole consuming a nearby star, imaging the formation and expansion of a high-speed jet of material ejected in the maelstrom.
Astronomers have made a bizarre discovery; a star that refuses to stop shining.
