At first, astronomers suspected that 1987A was a class of supernova known as type 1a — the detonation of a stellar core left behind after a star like the sun quietly sheds gas at the end of its life.

After shining for many millions of years, stars end their lives, mainly, in two ways: very high mass stars die very violently as supernovae, while low mass stars end as planetary nebulae.
