The greatest light show on Earth
Could our planet be under attack from the unearthly forces that cast a mysterious glow across the poles, disrupting life as we know it?
The strange, beautiful coloured lights that circle the Earth's polar regions are a source of fascination for many.
But as the Aurora Borealis, or Northern Lights, dance in the frozen skies over Alaska, scientists' trigger fingers are poised to launch rockets.
The researchers at the world's largest land-based rocket range hope to learn more about these storms and their impact on lives in the northern hemisphere.
The luminous sheets of light might look spectacular, but they are also visual indicators of geomagnetic storms in space that can interfere with satellites, power grids, navigation and communication systems. They can even corrode oil pipelines.
It is this disruption that the researchers are trying to help mitigate.
