What’s going on at the largest single-dish radio telescope in the world? The Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China has discovered a new assortment of highly magnetized, pulsating neutron stars in more than a dozen of our Milky Way galaxy's globular star clusters. Called millisecond pulsars, these ultracompact remnants of stars that exploded as supernovas are sped up to dizzying rotation rates as they siphon gas off their stellar companions, as depicted in this illustration. To learn about what these so-called millisecond pulsars might tell us about stellar evolution, read our AAS Nova article and the research report on which it's based in the Astrophysical Journal Letters.
