A hedgehog on the Sun? It’s more likely than you think.
Staring into the Sun is dangerous — unless you’re an orbiter full of metals and coated in a layer of protective calcium phosphate.
For ESA’s Solar Orbiter, getting blasted by the Sun’s energy is no sweat.
This week, the European Space Agency released a trove of new videos and photos from that encounter, including the sharpest view ever captured of the Sun’s south pole.

Researchers aren’t sure what exactly the hedgehog is or how it formed.
