SVEMIR – No, it's not a portal to a foreign world. On the night of Monday, March 4-5, a swirl of white light lit up the Arctic sky, prompting many questions from netizens. But this phenomenon is truly human, as Live Science explains.

The scene, made even more surreal by the play of colors of the aurora borealis, was captured by photographers in Finland, Iceland and Norway. In reality, at the origin of this mysterious spiral, which you can see in the video at the top of this article, is something quite ordinary in our atmosphere: the launch of the Space X rocket.

Last Monday, the American company launched the Falcon 9 rocket into space, which will carry fifty satellites into orbit around the Earth. After completing its mission, the rocket separated from its second stage, which fell back into the atmosphere and burned up (unlike the first stage, which can be reused). During this operation, the remaining fuel was dispersed into space.

It is this fuel, frozen in the form of tiny crystals, reflecting the sun's rays, that would create this spectacle. If this spiral does not form with every rocket launch, it is because it depends on several factors, including the orientation of the rocket relative to the Earth and the Sun.

However, this is not the first time that these vortices, aptly named “Space X spirals”, have appeared. Already in 2023, for example, the same spectacle was seen in Hawaii. According to astronomers, these events should appear more and more frequently, as the launch rate increases.
