Three-Dimensional Distribution of Dark Matter in the Universe (with 3 slices of time)
This three-dimensional map offers a first look at the web-like large-scale distribution of dark matter, an invisible form of matter that accounts for most of the universe's mass. This milestone takes astronomers from inference to direct observation of dark matter's influence in...

Comparison of Normal Matter and Dark Matter's Large Scale Structure
These two false-color images compare the distribution of normal matter (red, left) with dark matter (blue, right) in the universe. The brightness of clumps corresponds to the density of mass. The map covers an area of sky nine times the angular diameter of the full Moon, and is...
COSMOS Field Compared to Other Hubble Surveys
Hubble Space Telescope has a narrow field of view, which is only a fraction of the angular diameter of the Moon. Certain research programs have devoted a substantial amount of Hubble observing time to survey comparatively larger areas of sky to address a wide range of galaxy...
Full Resolution Image Single HST ACS COSMOS Tile
This image covers one of 49 COSMOS tiles. It is created from ACS infrared data as well as Subaru broadband data. This tile is roughly 10 arcminutes in size. It is one-third of the full resolution COSMOS tiles. The Subaru image is courtesy of P. Capak and R. Massey (Caltech).
