Nasa reveals mesmerising footage of Northern Lights from ISS amid ‘severe’ geomagnetic storm warning --[Reported by Umva mag]

A NASA astronaut has revealed a stunning timelapse of the Northern Lights taken from the ISS.

And the footage comes just ahead of another geomagnetic storm which is expected to leave spellbinding views once again

Auroras are one effect of such energetic particles.
These particles can speed out from the sun from giant eruptions known as coronal mass ejections or CMEs and solar flares, explosions of radiation on the sun.
After a trip toward Earth that can last two to three days, the solar particles and magnetic fields cause the release of particles already trapped near Earth, which in turn trigger reactions in the upper atmosphere in which oxygen and nitrogen molecules release photons of light
The result: the Northern and Southern lights.
