Possible Creation of a Black Hole

Black hole possibly caught in creation, CNN
A star, SN 1986J, which is 30 million lightyears away, went supernova in 1983. When it runs out of fuel, the core collapses into a neutron star, and the outer shells of the star explode outward. If the core has a mass less than 1.4 times the mass of our star, it remains stable as a neutron star. If the core has a mass greater than 1.4 times the mass of our star, it will continue to collapse, creating a blackhole. At least, this is what happens in theory. Scientists are surprised that they are able to see what’s going on through the expanding outer layers. The fact that they can suggests that there is a crack in that shell. They’re not exactly sure what’s going on. And they don’t know if it’s going to be a black hole, a neutron star, or possibly something else. It would be the first time we’ve witnessed either, and it’s pretty cool, no?
