A supernova, is the catastrophic gravitational collapse of a stellar (star) core having a mass greater than 3.5 times the mass of the Sun. This is the last stage of the evolution of a star on the main sequence (Hertzsprung-Russell Diagram), and which ends in a violent explosion of the star's core, when nuclear forces prohibit any further collapse of the star, leaving behind a neutronium core, making it a neutron star. Supernovae are the most energetic stellar events in the known universe.
In 1989, a star in the galaxy M66, in the constellation Leo, underwent a supernova core collapse, which left stellar remnants in the form of a planetary nebula.

An adjective describing something really, really cool. When used as a compliment, it is the highest form of flattery. See also, rockstarific and rad.

Person two: Yah, it's really sweet!
Person one: Just about supernovaical!

Something that is incredibly hot, or much hotter than you expect it to be.
It somehow defies logic as to how it got that hot.
