Our Sun has been quite active over the past several weeks, ejecting giant strands of stellar debris into the cosmos. NASA scientists recently captured a video of one particularly eye-catching explosion that produced a dramatic arch across the sunā€™s surface.

This eruption, which occurred on June 18, 2015, grew into a substantial coronal mass ejection (CME), which arrived as a mild geomagnetic storm on Earth several days later.

The NASA video shows the bursts at extreme ultraviolet wavelengths to highlight material in the low parts of the Sunā€™s atmosphere, which is colorized in red. The entire clip covers about four hours of the event.
