The new era of multimessenger astronomy has substantially boosted studies of neutron stars. Timing of radio pulsars has produced precise neutron star masses and holds the promise of a moment-of-inertia measurement. X-ray observations of accreting neutron stars led to the first tight constraints on their radii. The first detection of gravitational waves from coalescing double neutron stars with LIGO already yielded information about their tidal deformability. In this talk, I will describe a framework that allows us to combine this trove of multimessenger information to measure the equation of state of neutron star matter. I will show that all current data point toward small (~11 km) radii for neutron stars. I will discuss the implications of these results for nuclear physics as well as the prospects of improving these measurements in the near future.
