Space.com is carrying this report on new studies of neutron stars and how they are constructed. By using new X-ray instruments, scientists were able to gain much more detailed information about the size, composition, and spin of one of these hyperdense celestial objects. Because the matter in a neutron star is in such an extreme environment (an object not quite twice the mass of the sun compressed into a form about as wide as Mount Everest is tall, spinning around 45 times a second), getting detailed observations can provide insight into the nature of matter itself.

Plus learning about a substance that would weight a billion tons per teaspoon is just flat cool. No, Ron, you can't have any.
