Auriga's Wheel is a newly uncovered collisional ring galaxy in the constellation of Auriga, the Chariot. It was discovered by Blair C. Conn (Max Planck Institute for Astronomy, Germany) who was lead investigator for the observational analysis, myself (Richard Lane, Universidad de ConcepciĆ³n, Chile), and collaborators. The simulation was produced by Rory Smith at the Universidad de ConcepciĆ³n, Chile, who was lead investigator for the theoretical analysis and the movie was produced by Rhys Taylor (Arecibo Observatory, Puerto Rico) from Rory's simulations.

The movie shows the collision between a spiral and an elliptical galaxy which well reproduces the properties of Auriga's Wheel. The movie pauses at the current view (i.e. how we see the object in the sky right now) and following the pause the future evolution is shown, with the two galaxies eventually merging completely.

for the original images, and some discussion, of the object.
