red stars

Dying giant suns

Red stars are stars with relatively cool surface temperatures, appearing reddish-orange to the eye.

They include red giants—aging stars that have expanded and cooled—and red dwarfs, the most common type of star in the universe.

In political contexts, a red star is a symbol of communism and socialist movements, appearing on Soviet flags and military insignia.
