 The most supernova explosions involve just one star, but Type 1A supernova involve a binary star system with a normal star and a white dwarf. But no one has ever found an exploding star's companion. In 2017, a group of astronomers used Hubble to study the remnant of the Type 1A supernova explosion, N103B, located in the LMC, where they may have finally found one. Using the exploding star's remnant curved shock fronts, they located the center of the explosion and found a candidate star nearby. The star has the right temperature, luminosity, and distance from the center of the original supernova explosion, although this star is a reasonable contender for N103B's surviving companion, its status cannot be confirmed yet without a spectroscopic confirmation. The research is still ongoing.
