Mystery solved about mysterious object at the center of a supernova. Using the James Webb Space Telescope, researchers were able to take a look into the otherwise hidden center of the supernova remnant.
“We now know that there is a compact source of ionizing radiation there, which is probably a neutron star. This was predicted by the explosion models, and we ran simulations in 1992 that showed how this might be observed. However, it was only with JWST that it really became possible,” explains Claes Fransson, professor at the Institute of Astronomy.
