Two tiny dwarf galaxies have wandered from a vast cosmic wilderness into a nearby "big city" packed with galaxies. After being in a quiet inactive period for billions of years, they are ready to party by starting a firestorm of star birth. Hubble Space Telescope has captured the glow of new stars in these small, ancient galaxies, called Pisces A and Pisces B.
