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.
