Astronomy Tuesday


Galaxy M94 is notable for that bright shiny bluish ring around the circumference, like a gaudy sequined tiara worn by a Halloween princess.

Those are all baby stars, bright and hot and blue, only a few million years old, which in galactic terms means they're barely old enough to cross the street by themselves. Galaxies with this type of intense star formation are called, appropriately enough, starburst galaxies, and no one really knows why some galaxies do this while others reproduce with more decorum.
