File:Galaxy rotation under the influence of dark matter.ogv|Left: A simulated galaxy without dark matter. Right: Galaxy with a flat rotation curve that would be expected with dark matter.
File:Gravitational lens-full.jpg|Gravitational lensing bends light around a massive object from a distant source. The orange arrows show the apparent position of the background source. The white arrows show the path of the light from the true position of the source.
File:Rotation_Curve_UGC11455.svg|The rotation curve of spiral galaxy UCG11455. The observed rotation for spiral galaxy UCG11455 is shown as points. The expected rotation from normal matter is shown in the line below.
File:A slice through the Universe.webm|The positions in space of the galaxies identified by the VIPERS survey.
File:Bullet cluster.jpg|X-ray photo by Chandra X-ray Observatory of the Bullet Cluster (1E0657-56). Exposure time was 0.5 million seconds (~140 hours) and the scale is shown in megaparsecs. Redshift (z) = 0.3, meaning its light has wavelengths stretched by a factor of 1.3. Based on today's theories this
File:SNIacurva.png|Type Ia supernova luminosity relative to the Sun ([[Solar luminosity|''L''0]]) versus time shows the characteristic light curve for a Type Ia supernova. The peak is primarily due to the decay of [[nickel]] (Ni), while the later stage is powered by [[cobalt]] (Co).

File:Collage of six cluster collisions with dark matter maps.jpg|Collage of six cluster collisions with dark matter maps. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide.
