Sun’s mysterious pole and a ‘solar hedgehog’ revealed in closest-ever images of the sun

A new record-breaking set of images of the sun captured by the Solar Orbiter probe during its close pass of the star in March has been released, revealing a plethora of never-before-seen details, including a curious geyser of gas scientists have nicknamed the “solar hedgehog.”

During the pass, which took Solar Orbiter as close as one-third of the sun-Earth distance, the spacecraft also glimpsed the sun’s south pole. It was the first time that any telescope, space- or Earth-based, had captured such detailed images of this region of the sun, which scientists believe plays a key role in the generation of the sun’s magnetic field.
