When the central temperature of a contracting cloud of gas grows sufficiently high, it becomes a star—a gigantic, controlled, thermonuclear reactor, fusing hydrogen into helium and maintaining a constant luminosity and size.

Supernovae come in several types, based primarily on their spectra. This lecture focuses on the important, hydrogen-deficient subclass called Type Ia, in which a white dwarf robs gas from its companion star and then becomes violently unstable.

If a neutron star exceeds two to three solar masses, it becomes unstable and collapses. The resulting object is called a black hole—a region of such extreme space-time curvature that nothing, not even light, can escape.

The imploding core of a Type II supernova typically forms a bizarre, enormously compact object called a neutron star, consisting entirely of tightly packed neutrons, a teaspoon of which would weigh about a billion tons.
