Hot blue starWhat is Gienah

It is a blue star 154 light-years away, several times hotter than the Sun and wrapped in a turbulent atmosphere mapped by telescopes. Its cold, electric light contrasts with the soft yellow background of nearby stars, like a blue ember kindled in the middle of a brazier.
