An optical image of the quasar RXJ1131-1231,
magnified by a gravitational lens. The red spot in the center
is the galaxy that is acting as a lens, while the four bright
spots (three top, one bottom) are magnified images of the same
quasar. Image courtesy of Ohio State University. |

A mosaic of X-ray images of the quasar
Q2237+0305, magnified by a gravitational lens. The bright spots
are four magnified images of the same quasar, which change in
brightness over time. Mosaic courtesy of Ohio State University. |

Magnification patterns of X-ray emission
for the quasar RXJ1131-1231. The patterns are created as light
emanating from near the center of the quasar -- the region where
material is spiraling into a black hole -- is magnified by a
gravitational lens. Image Courtesy of Ohio State University. |

emanating from the quasar's accretion disk is magnified by a
gravitational lens. Image courtesy of Ohio State University. |
