In this Hubble Space Telescope image, star birth is lighting up one end of the diminutive galaxy Kiso 5639. The dwarf galaxy is a member of a class of galaxies called 'tadpoles' because of their bright heads and elongated tails. This galaxy resides relatively nearby, at 82 million light-years away. Tadpoles are rare in the local universe but more common in the distant cosmos, suggesting that many galaxies pass through a phase like this as they evolve. Hubble observations of Kiso 5639 have uncovered the stellar content and bright pink glow of hydrogen at one end of the galaxy. A burst of new stars in a region measuring 2,700 light-years across makes the hydrogen clouds glow. The mass of these young stars equals about 1 million suns. The stars are grouped into large clusters that formed less than 1 million years ago. Hubble's observations were taken in February 2015 and July 2015 with Wide Field Camera 3.
