Double Einstein Ring

Somewhere far, far away...

a rude "little" boy is chuckling to himself
how the ants have just now noticed the magnifying glass
pointed in their direction...

This is an image of gravitational lens system SDSSJ0946+1006 as photographed by Hubble Space Telescope's Advanced Camera for Surveys. The gravitational field of an elliptical galaxy warps the light of two galaxies exactly behind it. The massive foreground galaxy is almost perfectly aligned in the sky with two background galaxies at different distances.
