It is said Nova is the creator of the universe, and therefor he is worshipped as a great and almighty god. However, very few actually revere him, instead regarding him as an entity beyond godhood. "If he's the one who made this world, who's to say he can't destroy it, too?" Yet even Nova cannot concoct a scenario that would bring about the utter decimation of creation.
See Star Destroyer Nova.
In general a nova (plural novae or novas) is an exploding star. A nova is a cataclysmic nuclear explosion on a white dwarf, which causes a sudden brightening of the star. A supernova is a stellar explosion that briefly outshines an entire galaxy, radiating as much energy as the Sun is expected to emit over its entire life span, before fading from view over several weeks or months. A luminous red nova (abbr. LRN) is a stellar explosion thought to be caused by the merging of two stars.
