Movie showing the time evolution in the Milky Way --- Sgr system over the last ~ 3 Gyr, followed by a fly-around view of the numerical model representing the Sgr stream as it is thought to look today. The blue spiral is the Milky Way disk, the yellow dot denotes the location of the Sun, and the orange/red ball is the Sgr dwarf. Note that the model Milky Way disk shown here is only intended to be a schematic representation.
