In the previous article, we examined white dwarfs and neutron stars, objects with the mass of a star compressed into a very small volume. Some of these objects could be what remains of a star that has collapsed in on itself. But what happens when mass is compressed into an even smaller volume?

In a star, the outward flow of energy generated by nuclear fusion in the core balances the inward pull of gravity. Without such fusion, a star would collapse into a very small volume. And indeed, the universe contains objects with a mass comparable to that of a star, but with a size comparable to the Earth. These are called white dwarfs.
