"We are a way for the cosmos to know itself."

-Carl Sagan

Left: Hubble Space Telescope image of galaxy cluster Abell 1689. This is one of the most massive structures yet to form in our universe. Its great mass bends space and acts as a gravitational lens, magnifying and distorting the images of galaxies more distant.

Right: Dark matter shown in blue as revealed in detail by our analysis of the observed gravitational lensing. Most of the matter in the universe is made of this invisible substance. We have yet to learn what it is.
