Scientists have developed the longest and most complex simulation to date of a binary neutron star collision that results in the formation of a black hole and a jet. The breakthrough will massively ...

A neutron star is what remains after a massive star goes supernova. Composed entirely of neutrons, this compact star possesses a radius of only a dozen kilometers (approx. 7 miles) but has a mass ...

The basic formula for producing a neutrino in a neutron star is straightforward: A neutron decays, transforming into a slightly-lighter, low-energy proton and an ultralight neutrino.

But things appear much differently for 4U 0142+61, which astronomers theorize had a violent history, even for a neutron star. It actually is solid, or so it appears. Approximately 100,000 years ...

The neutron star, known as PSR J0952-0607, was discovered in 2017 about 3,000 light-years from Earth in the constellation Sextans. Recent measurements show the star weighs 2.35 times as much as ...

What would happen if you put a baseball-sized piece of neutron star on the Earth? Would it fall to the core of the Earth and ...

Neutron stars are some of the densest objects in the universe. They are the core of a collapsed megastar that went supernova, ...

A new study finds that giant neutron stars can exist for a few milliseconds in a merger. ... Doctor Who’s Most Sitcom-Inspired Episode Rebooted a Winning Formula. Retrospective.

Astronomers have spied the heaviest neutron star to date 3,000 light-years away from Earth. The “black widow,” a dense, collapsed star that’s devouring its stellar companion, also spins 707 ...

Image shows evidence for a neutron star following a stellar explosion called Supernova 1987A in the Large Magellanic Cloud, a dwarf galaxy neighboring our Milky Way, in this handout combination of ...

Neutron stars are dead relics that have collapsed into very small, dense spheres with tough crusts. Forces welling from within can crack the crusts during events called star quakes, similar to ...

Neutron stars are like the most efficient thermoses in the universe, filled with hot noodle soup. Here's how, over the course of millions of years, they cool down.
