Recent observations of neutron stars in radio, visible and X-ray radiation are able to significantly constrain the properties of cold, dense matter. These observations include the discovery of a nearly 2 solar mass neutron star from pulsar timing, simultaneous mass and radius estimates from X-ray bursters and cooling quiescent stars, and detection of the rapid cooling of the Cassiopeia A supernova remnant. These have limited the range of equations of state for neutron star matter and severely restrict the roles that quark matter has in their interiors. Limits to the critical temperatures for a neutron superfluid and a proton superconductor in the core of neutron stars are also suggested.
