Impacts of space weather

Space weather describes events in space that can impact our lives here on Earth.

Space Weather explained: What is the Aurora Borealis?

The aurora borealis, or northern lights, occur because of space weather.

Space Weather explained: Geomagnetic Storm

A geomagnetic storm is a temporary disturbance in the Earth’s magnetosphere caused by a large burst of solar wind which interferes with the Earth’s magnetic field.

Space Weather explained: Coronal Mass Ejections and Solar Flares

Coronal mass ejections are an eruption of charged bubbles of magnetic gas from the sun and are often linked to solar flares that are sudden releases of large amounts of energy from the sun.

Space Weather explained: Solar radiation storm

A solar radiation storm occurs because of the interaction between charged particles, mainly protons, from the sun and the Earth’s magnetic field.

Space Weather explained: Solar wind and Coronal holes

The solar wind is the continuous outward flow of charged particles, primarily electrons and protons, from the sun. A coronal hole is a region of the sun’s corona with relatively low density and temperature.
