Galaxy Clusters: Giants of the Universe - Producer's Cut

Galaxy Clusters: Giants of the Universe - Trailer from Brian Hart on Vimeo.

The latest version of a new documentary project, "Galaxy Clusters: Giants of the Universe," is presented. Clusters of galaxies are the largest gravitationally bound objects in the Universe. A standard measure of their size extends from 3-15 million light-years (approx 1-5 Mpc) across. The warm gas in between the galaxies of the clusters reaches temperatures of 10 million to 1 billion Kelvins. This makes it shine brightly in the X-rays, and assuming that the gas is in hydrostatic equilibrium, the gas is used as a tracer of the dark matter content of the cluster. The high-level structure of galaxy clusters was studied by Dr. Hart through using Chandra X-Ray Observatory data to investigate the structure and behavior of the Universe as a whole.

The movie follows the story of Chandra and documents the achievements by women in space and astronomy. Dr. Hart leads us out from Earth to where the galaxy clusters roam in the depths of the Universe and tells the story of dark matter, dark energy, and the quest to understand the workings of the Universe.

"Galaxy Clusters: Giants of the Universe" is rated NR by the Motion Picture Association of America (MPAA).
