How Big Is a Solar Flare?
How big are solar flares? According to this video, pretty darn big. The solar flare in this video is roughly as long as 30 Earths lined up next to each other — normal for a solar flare.
A solar flare is a sudden release of energy from the sun's surface, usually composed of a mix of hydrogen gas and ultraviolet radiation. Solar flares typically erupt from active regions on the sun where magnetic fields are much stronger on average. NASA's Solar Dynamics Observatory captured this event, which combines a flare, a coronal mass ejection (CME) and a minor radiation storm.
