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 sun’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 Sun’s atmosphere, which is colorized in red. The entire clip covers about four hours of the event.
