The extraterrestrial object that slammed into the Earth 65million years ago and sparked the extinction of the dinosaurs was most likely a speeding comet, new analysis claims.
New research has suggested that the 110 mile-wide Chicxulub crater in Yucatan, Mexico, was caused by the impact of a smaller object than previously thought.
But for a smaller object to have caused such a cataclysmic impact it must have been moving at speeds usually only reached by comets hurtling through our solar system from outer space.
