Distant Milky Way-like galaxies reveal star formation history of the universe
Look at this new radio image covered with dots, each of which is a distant galaxy! The brightest spots are galaxies that are powered by supermassive black holes and shine bright in radio light. But what makes this image special are the numerous faint dots filling the sky. These are distant galaxies like our own that have never been observed in radio light before.
