NASA HiRISE Image: Mars Bullseye Crater

NASA's High Resolution Imaging Science Experiment (HiRISE) camera orbiting Mars spotted this 'bullseye' crater which has left scientists baffled as to how it was created. Experts from the University of Arizona are puzzling  whether the strange 'bullseye' shaped crater - half-a-mile wide - was formed by a meteor strike hit almost dead centre by a second meteor, or whether it was caused by a single impact reacting with different types of unusual subsurface layers in the ground
