We’re working to understand why up to 10 million jets of solar material burst from the sun’s surface at any moment. Called spicules, they can erupt as fast as 60 miles per second and reach lengths of 6,000 miles before collapsing. Now, for the first time, a computer simulation — so detailed it took a full year to run — shows how spicules form, helping scientists understand how they break free of the sun’s surface and surge upward so quickly.
