Compass and Scale Image for Overlapping Galaxies 2MASX J00482185-2507365
780 million light-years (240 megaparsecs)
This image is roughly 50 arcseconds (180,000 light-years or 56 kiloparsecs) wide.
HST Proposal: 10915 J. Dalcanton (University of Washington) et al. The science team comprises B. Holwerda and R. de Jong (Space Telescope Science Institute), W. Keel (University of Alabama, Tuscaloosa), and J. Dalcanton and B. Williams (University of Washington).
F475W (B), F606W (V), and F814W (I)
The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue: F475W (B)
Green: F606W (V)
Red: F814W (I)
