When it comes time for one to end it all in a supernova, there isn't as much matter left to collapse in on itself, resulting in a lower - mass black hole.

Black holes are thought to form when the dense core of a supernova — a massive, exploding star — collapses in on itself.

The research team concludes that the majority of core collapse supernovae, exploding in luminous infrared galaxies, have previously not been found due to dust obscuration and poor spatial resolution.

In a Type 2 supernova, a single star experiences a sudden collapse.

Quench cooling the gas, they observed the condensate to grow, then subsequently collapse as the attraction overwhelmed the zero - point energy of the confining potential, in a burst reminiscent of a supernova, with an explosion preceded by an implosion.

While it's known that Type 1a supernovae form from collapsing white dwarfs — the densest forms of matter after black holes and neutron stars — their formation theories come in two flavors: the single degenerate scenario in which a normal star is consumed by a white dwarf; and the double degenerate scenario in which two white dwarfs merge.

This animation shows a gigantic star exploding in a «core collapse» supernova.

Another kind of supernova, the «core collapse» variety, happens when a massive star ends its life in an explosion.

Since gamma radiation provides the energy preventing gravitational collapse of the outer layers of the star onto the core, at some point the loss of this energy (through so - called «pair instability») causes violent pulsations that eject a large fraction of the outer layers of the star and eventually a star's outer layers to collapse inward to create a thermonuclear explosion that, in theory, would be brighter than previously detected supernova.
