On the last day of August, the sun spit out a mass of gas controlled only by its own magnetic fields — and it was all seen by NASA’s Solar Dynamics Observatory.

The solar filment is described by NASA as collapsing “in a spectacular way” on Aug. 31. The observatory captured the scene in extreme ultraviolet light letting the “dramatic detail” of the event shine through.

“Long filaments like this one have been known to collapse with explosive results when they hit the stellar surface below,” according to NASA.
