Laboratory visualisation of solar wind interaction with Earth’s magnetic field. The Van Allen radiation belt, Earth’s magnetosphere, “bow shock” and a solar coronal hole can all be seen, and are emphasized with the ‘Planeterrella experiment‘, a vacuum chamber in the shape of a bell jar with the ‘Sun’ on the left (in the form of …[Read More]

This is a crossed polarized light photomicrograph of an impact spherule; a small mineralisation made when a meteorite hits the Earth and melts the rock at the point of impact, from Barberton Greenstone Belt, in South Africa. These spherules are the only remnants of Early Earth’s meteorite impact history, from between of 3.2 and 3.5 …[Read More]

Aurora Borealis, which means Northern Lights are caused by electrically charged particles from the sun, which enter the Earth’s atmosphere and collide with gases such as oxygen and nitrogen. When the charged particles are blown towards the Earth by the solar wind, they are largely deflected by the Earth’s magnetic field. However, the Earth’s magnetic …[Read More]
