NASA : Extreme Ultraviolet Image of a Significant Solar Flare

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido de la Agencia Espacial NASA una espectacular vista captada por :  NASA's Solar Dynamics Observatory y nos dice:  "El sol emite una llamarada solar significativa el 19 de octubre de 2014, alcanzando un máximo a las 1:01 am EDT. Observatorio de Dinámica Solar de la NASA, que siempre está observando el sol, captó esta imagen del evento en la longitud de onda ultravioleta extrema de 131 Angstroms - una longitud de onda que se puede ver el intenso calor de un brote y que es típicamente coloreada en verde azulado.......

Extreme Ultraviolet Image of a Significant Solar Flare
The sun emitted a significant solar flare on Oct. 19, 2014, peaking at 1:01 a.m. EDT. NASA's Solar Dynamics Observatory, which is always observing the sun, captured this image of the event in extreme ultraviolet wavelength of 131 Angstroms – a wavelength that can see the intense heat of a flare and that is typically colorized in teal.
This flare is classified as an X1.1-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 flare is twice as intense as an X1, and an X3 is three times as intense.
Solar flares are powerful bursts of radiation. Harmful radiation from a 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.
