Solar flares ☀️ Solar flares are huge bursts of energy released from the Sun. These intense bursts of radiation take just a few minutes to reach millions of degrees, and their effects can be devastating, causing blackouts and interfering with satellites. Solar flares sound scary, but they won't exactly destroy Earth. Occasional flares from the Sun could reach our planet if they are especially powerful, at which point they can cause damage to power grids. #freeAstroSci #FollowTheScience #scientif
