Its blown into interstellar space - to enrich and mix with the gasses already out there.
It is a supergiant.(the late stage in the life cycle of a massive starin which the core heats up, heavy elements formedby fusion, and expands; it can eventually explodeto what scientist call a supernova.)-Missy K
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
the outer core is 2300 km thick the inner core on the other hand is 1200 km thick.
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
Depending on the Mass of the core, they either become a Neutron Star or a Black Hole.

A neutron star
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).

Yes, if the star is massive enough when the core collapses a supernova explosion happens.
The core collapses
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
After a high mass star explodes, the leftover material forms a remnant called a neutron star or a black hole. If the core of the star is less than about 3 times the mass of the Sun, it collapses to form a neutron star. If the core is more massive, it collapses further, causing the gravitational collapse to form a black hole.
A black hole or a neutron star, depending on the mass of the remaining core. Also a lot of material is ejected into space.
