This image is a composite of separate exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F814W (I) Green: F105W (Y) Red: F160W (H)

This diagram shows how the gravity of the massive galaxy cluster Abell 2744 bends and magnifies the faint light of a far distant galaxy behind it, a phenomenon called gravitational lensing. The cluster's lensing power produced three magnified images of the faraway galaxy,...
