  • TINY GALAXIES BRIMMING WITH STAR BIRTH.  

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.   

The dwarf galaxies are typically a hundred times less massive than the 
Milky Way galaxy but are churning out stars at such a furious pace that 
their stellar content would double in just 10 million years. Hubble's Wide 
Field Camera 3 and Advanced Camera for Surveys spied the galaxies in the Great Observatories Origins Deep Survey South (GOODS South Deep) field. The galaxies' locations in the GOODS South Deep field are marked by circles in the large image.   

The galaxies stood out in the Hubble images because the energy from all the new stars caused the oxygen in the gas surrounding them to light up like a bright neon sign. The rapid star birth likely represents an important phase in the formation of dwarf galaxies, the most common galaxy type in the cosmos.   

The galaxies are among 69 dwarf galaxies found in the GOODS and other fields.   

Images of the individual galaxies were taken November 2010 to January 2011. The large image showing the locations of the galaxies was taken between September 2002 and December 2004, and between September 2009 and October 2009.

  • CANDELS DWARF GALAXIES.   

The CANDELS team identified 69 dwarf galaxies that are undergoing 
intense bursts of star formation. The dwarf galaxies were found in two 
regions of the sky called the Great Observatories Deep Survey-South and 
the UKIDSS Ultra Deep Survey (part of the UKIRT Infrared Deep Sky Survey). 
Each dwarf is shown centered in cutouts made from near-infrared (I, J, 
and H band) images acquired by Hubble's Wide Field Camera 3 and 
Advanced Camera for Surveys. The light from these galaxies has been 
traveling for about 9 billion years. Many of the stars in nearby dwarf galaxies may have formed in similar starbursts around the same time. The background shows a wider near-infrared view of the CANDELS Ultra Deep Survey field.
