NASA’s Solar Dynamics Observatory captures this video of a filament eruption on the sun last Friday at 4:36 in the afternoon EDT. The segment of the video in 304 angstroms wavelength, during which the sun appears red, covers a period of time lasting three hours.
The explosion sent a wave of solar plasma, known as a coronal mass ejection, toward the Earth at a speed of 900 miles per second, resulting in a beautiful aurora over parts of the Northern Hemisphere last night.
