The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

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." ...

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

"For the first time, we see the creation of atoms; we can measure the temperature of the matter and see the microphysics in this remote explosion." When you purchase through links on our site, we may ...

Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and ...

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 ...

In 1987, earthbound observers saw a star explode in the nearby dwarf galaxy called the Large Magellanic Cloud. Astronomers eagerly studied this supernova–the closest seen in the past 300 years–and ...

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen. When you purchase through ...
