Reconstruction of the path of the asteroid that exploded over Chelyabinsk, Russia, on 15 February 2013. This provides information about the origin, trajectory and power of the airburst. These details, published in a pair of papers in Nature, may help to refine theoretical models about the likely frequency of such events and potential damage. This 3D simulation by Mark Boslough was rendered by Brad Carvey using the CTH code on Sandia National Laboratories’ Red Sky supercomputer. Andrea Carvey composited the wireframe tail.
