Mapping Dark Matter

Description
Mapping Dark Matter
(Top) The Hubble Space Telescope observed that galaxies in the same direction,
but at different distances from Earth, undergo different amounts of gravitational
lensing. (Bottom) Much of this effect is due to dark matter. By subtracting out the lensing
effects of intervening galaxies, the distorted shapes of the galaxies at various
distances enable astronomers to determine the distribution of dark
matter.
