- Asteroid impact. Illustration of a large asteroid colliding with Earth on the Yucatan Peninsula in Mexico. This impact is believed to have led to the death of the dinosaurs some 65 million years ago. The impact formed the Chicxulub crater, which is around 200 kilometres wide. The impact would have thrown trillions of tons of dust into the atmosphere, cooling the Earth's climate significantly, whic
- Illustration of the K/T Event at the end of the Cretaceous Period. A ten-kilometre-wide asteroid or comet is entering the Earth's atmosphere as dinosaurs, including T. rex, look on.

- Earth from space. Computer illustration showing the Earth as viewed from space, centred over Central America. North America (upper) and South America (lower) can be seen.
- Artwork of the young Earth-Moon system. The Earth had recently formed when it was struck by a protoplanet " called Theia " roughly three times the size of Mars. Debris from the impact went into orbit where it quickly coalesced to form the Moon, probably within just a few thousand years. Initially the Earth and Moon were much closer together than they are now, and spinning more quickly. In this dep

- Illustration of the Chicxulub crater, shortly after its formation. This crater was formed 66 million years ago, off the coast of present-day Mexico, following the impact of an asteroid 10-14 kilometres across. The asteroid is widely believed to have provoked the extinction of the dinosaurs and other species at this time. The crater measures some 150 kilometres in diameter. Since its formation it h

- It is thought that comets may have seeded Earth's oceans. After the planets had largely formed, there was a period lasting several hundred million years, during which the young worlds continued to accrete debris, raining down from space. This was called the heavy bombardment phase. Much of this debris would have been in the form of comets, rich in water. In time, as these impacts began to subside
