On Sept. 30, 2014, multiple NASA observatories watched what appeared to be the beginnings of a solar eruption. A filament – a serpentine structure consisting of dense solar material and often associated with solar eruptions – rose from the surface, gaining energy and speed as it soared. But instead of erupting from the Sun, the filament collapsed, shredded to pieces by invisible magnetic forces. Because scientists had so many instruments observing the event, they were able to track the entire event from beginning to end, and explain for the first time how the Sun’s magnetic landscape terminated a solar eruption.
The study makes use of a wealth of data captured by NASA’s Solar Dynamics Observator...
