IC 1613 is an irregular dwarf galaxy, 2.3 million light years from earth. There is little dust associated with it which enables many background galaxies to be seen through it. IC 1613 helped astronomers work out how to utilize variable stars to determine the expansion rate of the universe. IC 1613 most closely resembles the nearby, transition-type dwarf galaxy Pegasus.
The dominant blue star clusters indicate on-going star formation. There is a bright HII region in the upper left which indicates ionized hydrogen due to new star formation.
