Was it a bird, a plane or a big sodding rock? The largest earth "impact" of recent times, the Tunguska event, might have left a crater after all. The impact levelled more than 2,000 square kilometres of forest in Siberia, but is thought to have been caused by an asteroid or comet exploding in Earth's atmosphere since no crater marking the impact has ever been found. Now researchers at the University of Bologna in Italy think they might have found a scar in the surface of the earth left by the 1908 astro-intrusion.â¦
