In a different kind of holiday light show, NASA is sharing video showing a significant solar flare that peaked at 7:28 p.m. on Friday evening.

The images were captured by NASA’s Solar Dynamics Observatory.

Solar flares are powerful bursts of radiation. This flare is classified as an X1.8-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
