News! The second mission of ESA astronaut Thomas Pesquet, who is currently on the ISS (International Space Station) captured in a spectacular video, the northern lights, how you have not captured me so far. As you can see in the video created by him and the European space agency (ESA), the northern lights are just below the place where Thomas caught her. 

This is part of the second part of the "Alpha" mission of ESA astronauts on the ISS.  

ESA said the camera used by the astronaut took 2 images/second. But, for better clarity, ESA edited them so that the images flow one after the other faster, thus transforming it into a video. Due to its technology, it made 25 images scroll per second, which means approx. 12-12.5 times faster than his real speed, if he had been let go, so now Thomas did.

However, this experiment that Thoms did to see the aurora borealis on the ISS was one of hundreds to do. According to ESA, it has to be as close as possible in space approx. 200 experiments. Of these: - 40 Europeans (ESA); - 12 French (CNES); - approx. 148 experiments conducted by different institutions or own experiments. 

Something about the Aurora 

Polar auroras are usually the most common.
These are just optical phenomena, without being stable in a certain place.
However, these horrors also have a specific place where they usually occur. They are found mostly in the polar areas and are very visible in the 6 months of the night in the polar areas.

How are they formed?

This topic was discussed a lot many years ago without an answer.
However, over time it has been shown that auroras are formed by impact
solar wind particles in the earth's magnetic field.
Thus, different colors of the northern lights are formed, the most common being: purple, green.
But there are other colors, found in smaller proportions.

Due to the human eye we see them chlorinated. Not so, the auroras are always black and white. Due to the fact that we have eyes, and our eyes perceive in a way the image seen in a certain space, we see them colored. In fact, anything in the universe according to scientists is in different shades of black, white and gray. But, unfortunately, we will not be able to be 100% secure, at least until now, because we have no other eyes than the ones we have now.

Also, the polar auroras do not appear only next to our atmosphere, but on the planet of each planet, at least to the planets in the Solar System.
