Galaxies that Fizzled Out Young
Some of these galaxies are especially interesting to astronomers and they have been highlighted in red in this new space picture. When the Universe was very young, the galaxies that have been highlighted were in a star-making frenzy, which is called a starburst. These starbursts didn’t last long and this is what astronomers are interested in: What put a stop to this rapid star production?
