Space: Death of a Star, Blackhole

What this episode covers

The main sequence of the star is coming to an end as its supply of hydrogen for nuclear fusion runs low. Without the counterbalance of the energy from nuclear fusion to fight the immense gravity, the star's core collapses in on itself. The outer layers expand, the inner core heats up and burns into heavier elements until finally, the newly created iron core collapses into a point of infinite gravity and density, or in other words, a blackhole.
