Impact craters are relatively shallow, so these bowl-shaped “dents” in Earth’s rocky crust can be easily buried or erased by erosion.
The trajectory of the Chicxulub asteroid led to the most efficient release of gas and projectile rocks – which was disastrous for life on Earth.

The Apollo missions to the Moon helped our understanding of the cosmic origin of craters on our lunar neighbour, and here on Earth.
Waves can be generated in lakes and other bodies of water when seismic energy travels through land.

If you’ve never heard of a form of wave called a ‘seiche’ – which can occur in swimming pools during earthquakes – this is your chance to catch up.

An asteroid on a collision course with Earth is inevitable. Astronomer Michael Lund explains how a new telescope under construction in Chile will become a vital tool for detecting objects that could devastate our planet.
