Cluster of bright white galaxies.
Text, Galaxy Cluster Abell 68. The arcs and streaks of light in this galaxy cluster, called Abell 68, are the magnified and distorted projections of galaxies lying far beyond the cluster.
One streak of light is circled.
Text, The light from the distant galaxies is bent and stretched by the cluster's powerful gravitational might.
A galaxy with two glowing red dots next to each other inside an oblong cloud of gas is circled.
Text, One galaxy's appearance is warped in a way that makes it resemble an evil-eyed alien invader.
