Extreme ultraviolet light streams out of an X-class solar flare was captured on March 29, 2014 at 1:48 pm by NASA’s Solar Dynamics Observatory.
The image blends two wavelengths of light: 304 and 171 Angstroms, which help scientists observe the lower levels of the sun’s atmosphere.
Solar flares are powerful bursts of radiation. Although this harmful radiation cannot penetrate the atmosphere to have a physical effects on human, it disturbs the layer of the atmosphere where communication and GPS signal travel.
According to Nasa, this flare is classified as an X.1-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.
