The cosmonauts saw a blue flash over Europe, they picked up almost the same unique thing over Slovakia

Astronauts from the International Space Station witnessed a mysterious flash of blue over Europe that no one seemed to notice. This unique phenomenon has its explanation, although until recently scientists did not believe that it existed, informs science alert gate.

opposite flashes

Thomas Pesquet, French astronaut for the European Space Agency, who arrived at the International Space Station In April of this year aboard the Crew Dragon spaceshipHe was just creating a time-lapse video of planet Earth.

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

This phenomenon occurs during classic storms, but occurs much higher in the atmosphere. As astronaut Bisquet explains, the cool thing about these lightning bolts is that they were sometimes seen by pilots several decades ago, when scientists were never sure of their existence.

As they saw it over Slovakia

Czech photographer Petr Horalek was also able to capture the red flashes of the ionosphere, also known as “elves”. He photographed the ones that formed over the High Tatras during a summer storm from the Czech Republic.

Although Pesquet herself does not explain what a particular phenomenon is, According to Science Alert . portal However, there is a blue ray in the image that has not yet reached the elongated crater stage. However, this may be due to the fact that it represents an interval and a relatively small number of images over a longer period of time. Among all these phenomena, we have only this one.

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

The International Space Station has a perfect view

How do CNET writes, the International Space Station is ideally placed to study and research similar phenomena that occur in the upper atmosphere, and tracking them from the surface of the Earth is difficult or sometimes impossible.

Pesquet also adds that these phenomena can also affect the global climate. However, how Scientists write in this year’s study, its influence on the chemical composition of the atmosphere is almost insignificant and its production of nitrous oxide can contribute to the chemical balance of the low thermosphere.

Blue rays were recently captured by the European Space Agency Using the gadget on the ISS and the camera. It was originally thought to be much rarer, but recent observations prove otherwise, and this phenomenon is probably more common than we thought.
