The Andromeda Galaxy: Distribution of Satellite Galaxies | Hubble Space Telescope
This animation begins with a view of the neighboring Andromeda galaxy, known as Messier 31 (M31). We zoom through a scattering of foreground stars and enter the inky blackness of intergalactic space. We cross 2.5 million light-years to reach the Andromeda system, consisting of 36 dwarf satellite galaxies orbiting the giant spindle-shaped Andromeda galaxy at image center. An ambitious survey by the Hubble Space Telescope was made to plot the galaxy locations in three-dimensional space. In this video we circle around a model of the Andromeda system based on real Hubble observational data.
