NASA shares a fascinating picture of the Northern Lights as seen from the International Space Station

NASA Astronaut Ricky Arnold captured this stunning image of the northern lights from the International Space Station (ISS).

We can call them "Northern Lights", but this image actually shows them on the southern hemisphere.

"Sunrise blocks an aurora party in the southern hemisphere," the astronaut said while sharing the image on Twitter. NASA picked it up quickly and made it the image of the day of last week.

"Auroras are one of the many terrestrial phenomena that the space station crew observes from their elevated position on the planet," the space agency said. 19659005] Read more



The ESA Swarm satellite takes images of the northern lights

"The dancing lights of the auroras provide spectacular views, but also capture the imagination of the scientists who study the incoming energy and particles from our Sun.

"Auroras are an effect of such energetic particles, which can leave the Sun in a constant current called solar wind or giant eruptions known as coronal mass ejections or CME.

After a trip to Earth that can last three days, the solar particles and the magnetic fields cause the release of particles already trapped near the Earth, which in turn trigger reactions in the upper atmosphere in which the molecules of oxygen and nitrogen release photons of light.
