For years, scientists have theorized that some black holes could actually be wormholes, and a new study shows that this space-time mimicry could in fact be possible.

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our ...

Sometimes a black hole is orbited by a neutron star—the dense corpse of a star also formed from a supernova explosion but which contains less mass than a black hole.

A black hole can spin around its axis like a planet, but with much greater strength because of its intense gravitational field. Scientists are increasingly discovering that some rapidly spinning ...

An artist's concept of a black hole orbited by a neutron star. Image: Caltech/R. Hurt (IPAC) When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to ...

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA's Chandra X-ray Observatory. This jet exists early enough in the cosmos that it ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

Astronomers have discovered a massive black hole jet that is three times bigger than the Milky Way. The jet is known as Quasar J1601+3102, and … The post The largest black hole jet ever ...

"The difference between a supercollider and a black hole is that black holes are far away, but nevertheless, these particles will get to us.” To unlock the secrets of dark matter, scientists ...

In a major breakthrough, scientists have simulated in unprecedented detail how a neutron star cracks just seconds before being swallowed by a black hole. The simulation, led by Caltech ...

In response, the black hole slowly drains the life out of the star, creating a bright, energy surge unlike anything we’ve ever observed before. “We’ve observed stars getting ripped apart as tidal ...
