Distant Galaxy in Hubble Frontier Field Abell 2744
This is a Hubble Space Telescope deep image of galaxy cluster Abell 2744. The inset image shows the region around galaxy Abell2744_Y1, one of the most distant galaxies in the universe. The image shows the galaxy as it appeared 650 million years after the big bang. The galaxy lies far beyond the foreground Abell 2744 cluster, but its image has been magnified and brightened by a phenomenon called gravitational lensing in the cluster. This image was taken as part of the Frontiers Fields Program.
