Supernova is the debut studio album by American band Today Is the Day, released in April 1993 by Amphetamine Reptile Records.

[2] In 2008, a remastered version of the album, including tracks from the band's "I Bent Scared" 7" single, was released via Steve Austin's self run SuperNova Records.

Patrick Kennedy of Allmusic awarded it 4 and a half out of 5 stars, hailing it as a "landmark recording" that "indicates that metal could indeed be far more than a simple, formulaic system of chugging riffs, screamed vocals, and stampeding drums.

[4] In an interview with the Lords of Metal fanzine, Steve Austin showed much satisfaction with older Today Is the Day work, mentioning how both Supernova and its successor Willpower are "the most fucked up albums that have ever been on planet Earth" and even suggested that the album played a key role in the development of heavy metal music, citing that artists such as The Dillinger Escape Plan and Botch were influenced by the sound of Today Is the Day.

[7] Deadguy drummer Dave Rosenberg, who was briefly a member of Today Is the Day in 1996,[8] described Supernova as one of his favorite albums of all time.
