The flames flared and sparked, casting short-lived stars out among the snowflakes.
As gas enters a density wave, it gets squeezed and makes new stars, some of which are short-lived blue stars that light the arms.
As many of you know, this cluster has been the source of numerous supernovae over the past twenty million years, due to its abundance of hot, short-lived stars.
Core collapse supernovae are only found in galaxies undergoing current or very recent star formation, since they result from short-lived massive stars.
There are four H II regions powered by short-lived, O-class stars.
Studies of ancient meteorites reveal traces of stable daughter nuclei of short-lived isotopes, such as iron-60, that form only in exploding, short-lived stars.
Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked eye examples, including some of the brightest stars in the sky.
Some nebulae are formed as the result of supernova explosions, the death throes of massive, short-lived stars.
The short-lived, blue stars forged in these regions emit copious amounts of ultraviolet light, that ionize the surrounding gas.
Massive short-lived stars exploded in supernovae that caused more star formation, triggering yet more supernovae, ultimately resulting in an expanding shell.
