The lifespan of a star is determined by its mass, so that a bunch of a certain age contains stars at different stages of their life, this which gives the opportunity for a detailed analysis of the cycles of stars, explains NASA .
The cluster that we can see on the photo published in Instagram contains some of the most massive known stars. These giant stars live fast and die young, burning their fuel at incredible speed and thus ending their lives in supernova explosions.
Star clusters give astronomers important clues to understanding the origin of massive star formation in the early universe, concludes NASA .
