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

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

Astronomers have witnessed a rare cosmic event, where a massive star in the Andromeda galaxy (M31) has transformed directly into a black hole, without the usual supernova explosion. The phenomenon ...

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

This is not carelessness, but the possible discovery of a rare stellar event in the Andromeda galaxy. A red supergiant star ...

hydrogen-depleted supergiant star in the Andromeda galaxy (M31) failed to detonate as a supernova. The research is “The disappearance of a massive star marking the birth of a black hole in M31.” ...

You’re out in the cold to find the Andromeda Galaxy, the next-door neighbor to our own Milky Way Galaxy, home to our sun and possibly another 300 billion or so stars, and Lord knows how many ...

Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, ...

Recent results suggest these exotic objects just might help us account for the mysterious force pushing the universe apart.
