Astronauts spotted a blue glow over Europe and captured a similar unique phenomenon over Slovakia

Astronauts from the International Space Station saw a mysterious blue glow over Europe that no one from Earth noticed. The unique phenomenon has an explanation, but until recently, scientists didn’t even believe it existed. Informs the Science Alert portal.

The European Space Agency’s French astronaut Thomas Pesquet has arrived at the International Space Station. aboard the spaceship Crew Dragon in April of this yearwas simply creating a time-lapse video of planet Earth.

However, when he looked at his creation, he was pleasantly surprised. He was able to capture a relatively rare phenomenon known as the transient light phenomenon or ionospheric lightning. It looked like a blue lightning bolt over Europe, and a few red lightning bolts above it, similar to classic storm lightning, only upside down.

This phenomenon occurs during classical storms, but is much higher in the atmosphere. As astronaut Pesquet explains, the fascinating thing about these lightning bolts is that they were sometimes seen by pilots a few decades ago, and scientists can never be sure of their existence.

They’ve also seen them over Slovakia.

Czech photographer Petr Horálek also managed to capture red ionospheric flashes, also known as “elves”. Photographed from the Czech Republic over the High Tatras during the summer storm.

Although Pesquet himself does not explain how special a phenomenon this is, According to the Science Alert portal however, there is a blue ray in the image that has not yet reached the extended breast stage. However, it may be because this is a time lapse and relatively few images over a longer period of time. Of the whole phenomenon, we have only this.

However, it is more likely a shorter blue ray that does not reach the higher parts of the atmosphere and therefore shines much brighter. This phenomenon lasts only a few milliseconds, at best a few seconds, and is very difficult to capture in a photograph.

The ISS has excellent vision

How writes CNETThe International Space Station is in an excellent position to study and investigate similar events occurring high in the atmosphere, and tracking them from the earth’s surface is difficult or sometimes impossible.

Pesquet adds that these phenomena can also affect the global climate. However, how scientists write in this year’s studytheir effects on the chemical composition of the atmosphere are negligible, and their production of nitrous oxide can contribute to the chemical balance of the lower thermosphere.

The Blue Rays were recently captured by the European Space Agency. Using a vehicle and a camera on the ISS. They were originally thought to be much rarer, but recent observations prove the opposite, and this phenomenon is probably much more common than we thought.
