Effects of Dark Energy
Description: This animation shows the expansion history of the Universe by modeling the Universe as a two-dimensional grid of galaxies. The Big Bang, shown as a flash of light, is immediately followed by rapid expansion of the Universe. This expansion then slows down because of the gravitational attraction of the matter in the Universe. As the Universe expands, the repulsive effects of dark energy become important, causing the expansion to accelerate. The size of the deceleration and acceleration has been exaggerated.

Spacecraft: COBE Informational Video
Description: This informational video features NASA's Cosmic Background Explorer (COBE) satellite, which rocketed into Earth orbit on Nov. 18, 1989 and quickly revolutionized our understanding of the early cosmos. This video was reissued by NASA for COBE's 20th Anniversary.

Type Ia supernova
Description: An animation showing a binary star system in which a white dwarf accretes matter from a normal companion star. Matter streaming from the red star accumulates on the white dwarf until the dwarf explodes. With its partner destroyed, the normal star careens into space. This scenario results in what astronomers refer to as a Type Ia supernova.
