Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the universe. A typical neutron star has a mass a few times the mass of the sun, compressed into a region only a dozen kilometers across. In the outermost layers of neutron stars, the density is billions of times greater than the density of a diamond.

Let's turn the sun into a telescope. In fact, we don't have to do any work—we just have to be in the right spot. But how can the sun be a telescope? The sun is not a mirror, but it is a lens. And we understand it's a lens through the magic of gravity.
