Something Strange Is Happening on the Sun, and We've Never Seen It Before [View all]

This past week, a part of the sun’s surface broke off and started circling the sun’s north pole almost as if it were a giant polar vortex––and scientists don’t know why.

Space weather forecaster Tamitha Skov posted a video of the phenomena to Twitter, sharing her excitement.

“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,” she wrote. “Implications for understanding the Sun's atmospheric dynamics above 55° here cannot be overstated!”

The find is just the latest in a series of interesting space observations thanks to the capabilities of the James Webb Space Telescope. According to NASA, solar prominence is a large bright feature that extends outward from the Sun's surface. Prominences consist of hydrogen and helium, and usually erupt when a structure becomes unstable and bursts outward, releasing the plasma.

Scott McIntosh, a solar physicist and deputy director at the National Center for Atmospheric Research in Boulder, Colorado, told Space.com that he has never seen a vortex like this but notes that something odd usually happens at the sun's 55 degree latitudes once every solar cycle.

It isn't that it's never happened, likely, but we never had the equipment to see it!
