Astrophysicists have analyzed two decades-worth of X-ray data and discovered three events inside galactic cores that can be interpreted in only one way: stellar destruction.
18 August 2014, 07:01 AM ET
The existence of medium-size black holes has been a matter of debate. But researchers say they have now confirmed such an object in the nearby galaxy M82 — a black hole about as massive as 400 suns.
07 August 2014, 02:01 PM ET
Black holes may have grown incredibly rapidly in the newborn universe, perhaps helping explain why they appear so early in cosmic history. Early black hole may have sucked matter in from all around, rather than just from an accretion disk.
06 August 2014, 05:00 PM ET
The full-length trailer for the Hawking biopic, which is called "The Theory of Everything," came out today (Aug. 6). The 2.5-minute trailer shows that the film will focus heavily on the relationship between Stephen Hawking and his first wife Jane.
