NASA’s Solar Dynamics Observatory (SDO) captured this imagery of a mid-level solar flare – as seen in the bright flash – around 8:30 pm EDT on April 17, 2016.Solar flares are powerful bursts of radiation. Harmful radiation from @ flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however – when intense enough – they can disturb the atmosphere in the layer where GPS and communications signals travel. The flare shown here was of moderate strength @nd only caused brief radio blackouts, according to NOAA’s Space Weather Prediction Center.
This video was captured in several wavelengths of extreme ultraviolet light, a type of light that is typically invisible t0 our eyes, but is color-coded in SDO images for easy viewing.SDO observes the sun constantly to help scientists understand what causes eruptions like these.
