The irregular dwarf galaxy IC 1613 is a member of the
Local Group of Galaxies. It can be found inside the constellation
Cetus in a distance of 2.4 million light-years. IC 1613 has played
an important role in the calibration of the period luminosity relation of
Cepheids for estimating distances, because an unusually low abundance
of interstellar dust both within IC 1613 and along the line of sight
enables especially accurate distance estimates.
Four distant galaxy clusters are also visible in the above image:
•
GxCl 01 (MCXC J0105.0+0201) with redshift z = 0.197 (light-travel time
= 2.3 billion years)
•
GxCl 02 (NSCS J010328+022246) with redshift z = 0.280 (light-travel time
= 3.1 billion years)
•
GxCl 03 (NSCS J010529+023128) with redshift z = 0.250 (light-travel time
= 2.8 billion years)
•
GxCl 04 (NSCS J010525+023904) with redshift z = 0.140 (light-travel time
= 1.7 billion years)
