With the recent activity on the Sun, we’ve used the words “massive” or “huge” to describe solar flares. But just how big are they, really? This great video explains and illustrates the actual size of solar flares.

Thanks to Scott Stevenson for creating and sending us the video. Scott notes that text subtitles are available if you click on the “CC” button on the bottom of the video screen, making this informative video accessible to a wider audience.

Excellent video for some true mind-blowing perspective! Thanks. I feel positively sub-atomic in size after watching that!
