Question

Quizplus · Accepted Answer

SN 1987A is classified as a Type II supernova because it was caused by the core collapse of a massive star. This is different from Type I supernovae, which are caused by the explosion of a white dwarf star. Type Ib supernovae are also caused by the core collapse of a massive star, but they have lost their outer envelope of hydrogen before exploding, making them distinct from Type II supernovae.
