Researchers at NASA were baffled when they saw a piece of the Sun, breaking off from its surface and creating a vortex around its North Pole. Scientists are still trying to understand what impact this event will have on Earth, and when.
Talk about Polar Vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star. Implications for understanding the Sun’s atmospheric dynamics above 55° here cannot be overstated! pic.twitter.com/1SKhunaXvP

Space weather forecaster Tamitha Skov shared a video sequence to Twitter late last week that shows a huge filament of solar plasma breaking free from the Sunâs surface.
âTalk about polar vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our star,â she tweeted of the footage, taken by NASAâs Solar Dynamics Observatory.
âOver 55° here, the implications for understanding the sunâs atmospheric processes cannot be emphasised!â
According to Space.com, this is the first time such a vortex has been spotted, due to the James Webb Space Telescopeâs exceptional capabilities. While scientists have seen filaments break out from the Sun before, this is the first time theyâve seen one generate a polar whirlwind.
Scott McIntosh, a solar physicist and deputy director of the National Center for Atmospheric Research in Boulder, Colorado, told Space.com that while heâs never seen a vortex like this, he does know that something weird happens once every solar cycle, or 11 years, near the Sunâs 55 degree latitude.
More observations of the #SolarPolarVortex reveal it took roughly 8 hours for material to circumnavigate the pole at approximately 60° latitude. This means an upper bound in the estimation of horizontal wind speed in this event is 96 kilometers per second or 60 miles a second! pic.twitter.com/EpHhwdLeDs
