The galaxies in the early universe were much smaller than our Milky Way and churned out stars at a rapid pace. They grew larger through mergers with other dwarf galaxies to eventually build the magnificent spiral and elliptical galaxies we see around us today. But astronomers using the Hubble Space Telescope have looked at two small galaxies that were left off the star party list. For many billions of years Pisces A and Pisces B lived in a vast intergalactic wilderness that was devoid of gas, which fuels star formation. They got left out in the cold.
