Northern Lights illuminate west Wales and England's south coast

Residents across the UK were left stunned as the sky was illuminated by the spectacular colours of the Northern Lights on Friday and Saturday evenings.

The natural phenomenon, known as the Aurora Borealis, is the result of increased solar activity.

Such occurrences are mostly visible near the Arctic Circle and northern Scotland, but particularly strong activity levels meant they could be seen as far south as Devon, Hampshire and Kent on Saturday night.

The Met Office has said sightings could continue to be possible during clear skies until Tuesday.

Northern Lights are caused by powerful solar eruptions from the Sun, called coronal mass ejections (CMEs).

Towards the end of last week, the Sun was observed to unleash CMEs directed towards the Earth.

This stream of charged particles can get captured by the Earth's magnetic field and directed into our atmosphere, especially towards polar regions.

When these charged particles collide with oxygen and nitrogen, photons of coloured light are emitted - this is the aurora.
