Lens Flare

Today's Astronomy Picture of the Day is a wonderful example of gravitational lensing: using the gravity of an object, such as a galaxy, to see other objects well beyond the reach of our current telescopes. Abell 68 (1.2 billion light years away) brings even further objects into view. "Mouseover" the image for some labels to help you identify the objects.
