The Chandra X-ray Observatory is the darling of high-energy astrophysics. Famed for providing unequaled x-ray views of ...

Some stars may transform into black holes without exploding into supernovae. Now, astronomers have finally spotted it as it ...

The explosion of the sun is a threat straight out of science ... Supernovae can give birth to black holes and neutron stars, ...

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

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

The explosion occurs when the star's fusion can no longer balance its intense gravity, leading to an inward collapse. The resulting supernova blast can outshine entire galaxies for months and ...

Stars have a life and death-cycle. Those that are about eight times more massive than the Sun explode as supernovae at the ...

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

Astrophysicists have observed an extraordinary event following the collision of two neutron stars—the explosive birth of a ...

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 ...

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