Animation of erupting volcanoes, lava flows and storms on the primordial Earth. The Moon is seen in the sky through the clouds. At this early stage, the Moon was far closer to Earth than it is now. During the Archaean Eon of the Earth's past, between...

Conceptual animation of the opening to a wormhole moving through a nebula. A wormhole (or Einstein-Rosen bridge) is a theoretical 'tunnel' through spacetime, allowed by the theory of general relativity. In principle, a wormhole connects two regions i...

In this cataclysmic scene, a city suffers a near-miss as an asteroid strikes in the distance. The effect of a large meteorite impact or meteor airburst over a city would be catastrophic, with extensive damage and loss of life. Asteroids that are 30 t...

We are a few thousand kilometres from Enceladus, a mid-sized icy moon of Saturn. In 2005, the Cassini spacecraft discovered that this relatively small world - only 500 km across - is, surprisingly, geologically active. Geyser-like jets of water were ...
