IC_1613

SRO

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.
There are many blue star clusters and there is a bright HII region in the upper left.

Incredible detail. Amazing how clearly the background galaxies reveal themselves, some extremely small and distant, yet appear to be fully developed spiral galaxies.
