A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star ...

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." ...

Astronomers have studied 3,600 supernovas to discover diversity in exploding white dwarf stars, a vital tool in the ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Astronomers have spotted an immensely powerful "zombie star" shooting through the Milky Way at more than 110,000 mph (177,000 km/h). The stellar cannonball, which has a magnetic field capable of ...

This artist's concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

A rapidly spinning neutron star orbits a smaller, helium-rich star very closely. This unique pair formed when a larger star exploded, leaving behind the neutron star which then interacted with its ...
