Movie

Title
Animation showing some characteristics of WIMPs WIMPs--Weakly Interacting Massive Particles
No one knows what dark matter is, but it constitutes 80 percent of the matter in our universe. By studying numerous dwarf galaxies — satellite systems that orbit our own Milky Way galaxy — NASA's Fermi Gamma-ray Space Telescope has produced some of the strongest limits yet on the nature of the hypothetical particles suspected of making up dark matter. Short, narrated video. Poster image, and dark matter simulations credit: Simulation: Wu, Hahn, Wechsler, Abel(KIPAC), Visualization: Kaehler (KIPAC) Watch this video on the NASAexplorer YouTube channel.
