Supergiant star

A supergiant star, in stellar classification, is a type of star of great mass and considerable brightness and size.

Supergiant stars are among the types of stars massive enough to end their lives as supernovae, with a massive explosion that collapses and ejects large amounts of gas and solid matter with a considerable amount of energy, sometimes leaving a remnant of a neutron star or black hole within a nebula of ejected stellar mass.

Notable supergiants
In a distant corner of the galaxy, an unnamed supergiant star went supernova at roughly the same time as the birth of Spock, many light years distant, on the planet Vulcan.
