Astronauts have filmed the incredible moment a solar storm lit up the skies, giving onlookers a stunning view of the Northern Lights.
The storm, thought to be the biggest since September 2005, was captured by astronauts at NASA's International Space Station on Monday.
A potent blast of magnetic plasma was said to have shot out of the sun on Sunday, travelling faster than usual before hitting Earth.
The celestial light show - known as a polar aurora - was so powerful that scientists believed it could damage Earth's power grid, as well as disrupting GPS signals.
Fortunately there were no reports of damage following the storm, according to space weather physicist Doug Biesecker US National Oceanic and Atmospheric Administration.
Auroras occur when fast-moving electrons from space collide with oxygen and nitrogen in Earth’s upper atmosphere.
They can feature red, blue, violet, pink, and white lights. Red lights tend to signify the most intense solar activity.
Astronaut Scott Kelly shared video and photographs on his Twitter feed of the dramatic moment the aurora could be seen above Earth's surface.
He wrote: "Yesterday's aurora was an impressive show from 250 miles up. Good morning from space_station! YearInSpace."
He later said: "Aurora I don't think I will ever see another quite like you again."
