Astronomers Discover Calvera, a Runaway Pulsar Racing Above the Milky Way
Astronomers have discovered Calvera, a pulsar speeding 6,500 light-years above the Milky Way’s disk. Formed from a supernova in a nearly empty region, Calvera challenges long-held ideas of star birth and death. Its discovery reveals that extreme stellar events can occur even in the galaxy’s sparse outer halo.
