The moment one piece of its north pole Sun detaches recorded the NASAan event that has not been observed before and has puzzled scientists.

The video shows a giant filament of plasma, or electrified gas, yes is launched from the sun, to separate and then wander into a “huge polar vortex”.

While astronomers are quite puzzled by the fact, they speculate that it has to do with the reversal of the sun’s magnetic field, which occurs once every solar cycle (ie once every 11 years).

The video was shared on Twitter by the space meteorologist Tamitha Skov, which she said was drawn from the NASA’s Solar Dynamics Observatory.

“We are talking about a polar vortex! Material from a northern bulge of the Sun has just been severed from the main filament and is now circulating in a massive polar vortex around the north pole of our star,” Skov shared in the tweet.

NASA describes solar filaments as clouds of charged particles that “float” above the sun, bound to it by magnetic forces.

These appear as elongated, uneven filaments that shoot from the sun’s surface.

Solar physicist Scott McIntosh, associate director of the National Center for Atmospheric Research in Boulder, Colorado, said: “Once every solar cycle, is formed at a latitude of 55 degrees this phenomenon begins to march up to the solar poles. It’s very strange. There is a big question around this. Why does it only move poleward once and then disappear and then magically return three or four years later to the exact same area?».

While astronomers have previously observed filaments breaking off from the sun, this is the first time that such a thing circulates in a whirlwind.
