Question:
Do stars flash different colours like blue, red, green, orange?



Replies:
Dear Lindsay,

Good question. Stars do not "flash" these different colors. However, stars do have real colors like the ones you suggest. They are not obvious but subtle reddish, bluish-white, and even greenish hues. If you look carefully at a rich field of stars you should see some that display these colors. But do not expect them to flash out at you. The colors are subtle.

Sincerely

David H. Levy
