Abell 1689 is a galaxy cluster in the constellation Virgo. It is one of the most massive galaxy clusters known.
From the image, the yellow galaxies belong to the cluster itself, however, the red and blue distorted streaks are background galaxies gravitationally lensed by the cluster. Some of the lensed galaxies are over 13 billion light years distant. The lensing zone itself is 2 million light years across.
