Hubble Heritage Gallery of Images. S Hubble Observes Young Dwarf Galaxies Bursting With Stars. NASA's Hubble Observes Young Dwarf Galaxies Bursting With Stars This image reveals 18 tiny galaxies uncovered by NASA's Hubble Space Telescope. The puny galaxies, shown in the postage stamp-sized images, existed 9 billion years ago and are brimming with star birth.
Hubble's Wide Field Camera 3 and Advanced Camera for Surveys spied the galaxies in a field called the Great Observatories Origins Deep Survey (GOODS). The galaxies are among 69 dwarf galaxies found in the GOODS (marked by green circles in the large image) and other fields. Images of the individual galaxies were taken November 2010 to January 2011. The large image was taken between Sept. 2002 and Dec. 2004, and between Sept. 2009 and Oct. 2009.

NASA Telescopes Help Discover Surprisingly Young Galaxy PASADENA, Calif. -- Astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, a mere 200 million years after the Big Bang. The finding addresses questions about when the first galaxies arose, and how the early universe evolved. NASA's Hubble Space Telescope was the first to spot the newfound galaxy. Detailed observations from the W.M. Keck Observatory on Mauna Kea in Hawaii revealed the observed light dates to when the universe was only 950 million years old; the universe formed about 13.7 billion years ago. Infrared data from both Hubble and the post-coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler.
This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity.
