Hubblecast 75: Dwarf Galaxies that Pack a Punch.
This new Hubblecast episode looks at starburst dwarf galaxies in a time when most of the stars in the Universe were formed. New NASA/ESA Hubble Space Telescope observations show that dwarf galaxies played a bigger role than expected in the early history of the Universe. This episode looks at the dwarf galaxies that form stars in sudden bursts, explores just how rampantly they are creating new stars and unravels when, where and how the stars in our Universe formed.
