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 in the universe - or two different regions in space ...Read more.

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 to 40 metres across are large enough to wipe out a ...Read more.

Conceptual image showing the magnetic field that surrounds and penetrates the planet Earth. Magnetic field lines emerge from the south magnetic pole, bend overhead and converge at the north magnetic pole, which is offset from the geographic north pole by 11 degrees. The exact position of the magneti ...Read more.

Sun analemma. Artwork of the analemma, the figure of eight shape made by plotting the position of the Sun at the same time of day during the year. The analemma is caused because the axis of the Earth's rotation is not perfectly perpendicular to the plane of its orbit around the Sun. This means that ...Read more.

This animation shows a supermassive black hole surrounded by a disc of gas and dust - the remains of stars that have been torn apart by the extreme gravity of the region. Owing to the incredible strong gravity, the disc around the hole is warped - a concept known as gravitational lensing. The lensin ...Read more.

Artwork of a black hole. A black hole is a region of spacetime where the gravity is so powerful that not even light can escape them. They are created when massive stars die. This one is surrounded by an accretion disc of material, the light from which is warped by the strong gravity. Both the front ...Read more.
