Computer simulation reveals asteroid's attack angle

The asteroid that wiped out the dinosaurs 66 million years ago hit Earth at a particularly lethal angle, scientists say. The steep angle maximised the amount of climate-altering material that was thrown into the atmosphere. Researchers worked out the trajectory by studying the different positions of key locations in the crater: the centre of the crater itself, the centre of a series of hills known as a peak ring, and the centre of uplifted rock under Earth's crust in its denser mantle.
