Dark Galaxies: Building Blocks Of Modern, Star-filled Galaxies Spotted

Dark galaxies, theorized but unobserved, may have been spotted. Dark galaxies are essentially gas-rich galaxies in the early Universe that are very inefficient at forming stars and astronomers think they have detected these elusive objects by observing them glowing as they are illuminated by a quasar. They are predicted by theories of galaxy formation and are thought to be the building blocks of today’s bright, star-filled galaxies. They may have fed large galaxies with much of the gas that later formed into the stars that exist today. read more
