A {{w|supernova}} occurs when a heavy star can no longer produce enough energy to fight its own gravity, e.g. because its fuel runs out ({{w|type II supernova|type II}}) or because it has accreted too much mass from a binary companion ({{w|type Ia supernova|type Ia}}). The collapsing mass leads to a violent explosion, one of the most interesting events for astronomers to observe and one that can be used to glean information about the universe. | A {{w|supernova}} occurs when a heavy star can no longer produce enough energy to fight its own gravity, e.g. because its fuel runs out ({{w|type II supernova|type II}}) or because it has accreted too much mass from a binary companion ({{w|type Ia supernova|type Ia}}).
