The Unification Epicenter of True Lightworkers
This image, and its associated movie, is illustrative of work by other astronomers, Kathryn Johnston of Wesleyan University in this case, to simulate the evolution of the interactions of dwarf galaxies like Sagittarius with the Milky Way through time. The animation, obtained by clicking on the image, begins when a Sagittarius-like dwarf galaxy was a compact, largely undisturbed system, and follows the Milky Way's disruptive influence over time as the dwarf orbits the Milky Way. If this were the Sagittarius system, this simulation would span approximately 2 billion years in the past through 500 million years into the future. Credit Kathryn Johnston/Wesleyan University.
