A neutron star is the collapsed core of a supergiant star that's gone supernova.
Pulsar neutron stars, like the one astronomers believe SN 1987A left behind, emit pulses of X-rays.
AdvertisementStudying SN 1987A has deepened astronomers' understanding of supernovae and the role they play in our ever-evolving universe.
Before JWST, astronomers lacked a telescope powerful enough to observe the compact object that SN 1987A left behind.
