SNIa

SNIa, or Type Ia Supernova, is a powerful explosion of a white dwarf star that occurs in a binary star system. When the white dwarf accumulates enough matter from its companion star, it reaches a critical mass and undergoes a cataclysmic collapse, leading to an explosive outburst. This explosion releases an immense amount of energy, briefly outshining entire galaxies. SNIa are significant in astronomy because they provide a consistent brightness, allowing scientists to measure distances in the universe and study the expansion of space.
