It doesn't necessarily make sense, said Stanek, professor of astronomy at Ohio State, that a massive star could undergo a supernova -- a process which entails blowing off much of its outer layers -- and still have enough mass left over to form a massive black hole on the scale of those that LIGO detected. This is called a singularity. This type of star is called a "white dwarf. What are neutron stars? By a careful process of elimination, the researchers eventually concluded that the star must have become a black hole. When a very massive star exhausts its nuclear fuel it explodes as a supernova. A team of astronomers at The Ohio State University watched a star disappear and possibly become a black hole. Rocket Size Comparison - Duration: Don't like this video?
When massive stars die, they don't just fade away. Their lives end in the most spectacular and most luminous explosions that we know.
For weeks they can. The radii of larger mass neutron stars (about prevent a star smaller than SR from collapsing to a. In collapsed stars, matter has been pushed to the limit. Internal pressures produced by nuclear power production in the centers of stars are no longer important.
Rocket Size Comparison - Duration: This is called a singularity.

Vologda Mapping 1, views. For small stars, when the nuclear fuel is exhausted and there are no more nuclear reactions to fight gravity, the repulsive forces among electrons within the star eventually create enough pressure to halt further gravitational collapse.
From the perspective of the collapsing star, the core compacts into a mathematical point with. Researchers have watched a massive star collapse directly into a black hole, unexpectedly skipping the supernova stage thought to occur in. Astronomers have watched as a massive, dying star was likely reborn as a black hole.
It took the combined power of the Large Binocular.

Anything, including light, that passes within the boundary of the black hole -- called the "event horizon" -- is trapped forever.

|Nuclear reactions in the core of the star produce enough energy and pressure to push outward.
Starting inone particular star, named NBH1, began to brighten weakly. This is called a singularity. It doesn't necessarily make sense, said Stanek, professor of astronomy at Ohio State, that a massive star could undergo a supernova -- a process which entails blowing off much of its outer layers -- and still have enough mass left over to form a massive black hole on the scale of those that LIGO detected.
