Nova

Definition of Nova

No´va   Pronunciation: nō´vå
n.1.(Astron.) A star which suddenly increases in brightness thousands of times, then fades back to near its original intensity. It may appear as a "new" star if its original brightness was too low for routine observation. A star which suddenly increases in brightness to many millions of times its original intensity is a supernova, and the postulated mechanisms for the increases of brightness of novae and supernovae are different.
