Abell 2744 Parallel Field (Frontier Fields)

In this field, Hubble resolved roughly 10,000 galaxies in visible light, most of which are randomly scattered galaxies. The blue galaxies are distant star-forming galaxies seen from up to 8 billion years ago; the handful of larger, red galaxies reside in the outskirts of the Abell 2744 cluster. This parallel field was captured as part of Hubble's Frontier Fields project, which used the combined power of "gravitational lenses" and Hubble's ability to create long-exposure deep field images to see galaxies that would normally be far beyond the reach of telescopes.
