+ * A nova occurs. It is the result of having a star hit with a
+ * photon torpedo, or possibly of a probe warhead going off.
+ * Stars that go nova cause stars which surround them to undergo
+ * the same probabilistic process. Klingons next to them are
+ * destroyed. And if the starship is next to it, it gets zapped.
+ * If the zap is too much, it gets destroyed.
