ESO FORS2 image of comet after impact

The FORS2 multi-mode instrument on Antu, one of the 8.2m Unit Telescopes of the ESO Very Large Telescope array, at the La Silla Paranal Observatory, took this stunning image on the evening of 4 July 2005, showing that the morphology of the comet had dramatically changed: a new bright fan-like structure was now visible.
