A combination of a Hubble Space Telescope image of SN 1987A and the compact argon source. The faint blue source in the center is the emission from the compact source detected with the James Webb Space Telescope. Outside this is the stellar debris, which contains most of the mass. The inner bright “string of pearls” is the gas from the outer layers of the star that was expelled about 20,000 years before the final explosion. The fast debris is now colliding with the ring, explaining the bright spots. Outside of the inner ring are two outer rings, presumably produced by the same process as forming the inner ring. The bright stars to the left and right of the inner ring are unrelated to the supernova.
