Archival images showed that the stars that gave rise to some supernovae were about 100 times as massive as the sun: according to accepted theory, stars this big were not supposed to explode.

Some supernovae may have been ther­mo­nuclear explosions triggered by the creation of pairs of particles of matter and antimatter.

The first generation of stars in the universe, which created the materials that later formed planets, may have exploded through a similar mechanism.
