Gravitational Lens Detail in Abell 370

About the colours

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 (G) Green: F625W (R) Red: F814W (I)

About the data

The Hubble images were created from data from proposal 11507 : K. Noll (STScI), M. Chiaberge (STScI/ESA/INAF), M. Mutchler, D. Golimowski, and R. Lucas (STScI), and M. Sirianni (STScI/ESA).
