Supernovae are divided into two basic physical types, Ia and II. Type Ia is caused by thermal runaway, and type II supernovae are caused by core collapse. Because the supernova "family tree" was laid out according to the light from supernovae, not their cause, there's technically also...
This blown-away material is sometimes called a "supernova remnant," which is a type of nebula. Sometimes if the exploded star was very massive, during the supernova, a long gamma-ray burst can also happen! Some of the shed material will get spun up around the resultant black hole or ...
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel...
