"Webb Telescope Discovers Neutron Star in Famous Supernova Remnant"

Using the James Webb Space Telescope, astronomers have discovered evidence of a neutron star in the remnants of supernova SN 1987A, which occurred 160,000 light-years from Earth in the Large Magellanic Cloud. The recent study provided the first direct evidence of the presence of a neutron star in the supernova remnant, resolving a mystery that has lasted for more than 30 years. The discovery was made by analyzing ionized argon atoms using Webb's Near-Infrared Spectrograph and Mid-Infrared Instrument, and the findings were published in the journal Science on Feb. 22, 2024.
