Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision ...

When the two neutron stars collide, the initial kilonova of exploded neutron star guts is extremely hot, billions of degrees, ...

Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, ...

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 ...

The kilonova briefly mimicked the conditions immediately following the Big Bang, and allowed scientists to confirm the source ...

The outward force from its fusion can no longer counteract the star's powerful gravity, and the star collapses in on itself.

this companion star is also massive enough to create a neutron star, and it isn't "kicked away" by the supernova explosion that creates the first neutron star. The result is a system with two ...

Astrophysicists have, for the first time, measured the temperature of elementary particles in the radioactive afterglow of a neutron star collision, which led to the formation of a black hole. This br ...

we can measure the temperature of the matter and see the microphysics in this remote explosion." Astronomers have witnessed the titanic collision between two neutron stars that resulted in the ...

In the binary system 4U 1820-30, a neutron star is spinning so fast around its center axis that it completes a breathtaking ...
