Significant Solar Flare in Extreme Ultraviolet

October 24, 2014 3:35 pm | by NASA | News | Comments

The sun emitted a significant solar flare on October 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.

NASA Captures Haunting Image of Jack-O-Lantern Sun

October 13, 2014 10:36 am | by Karen Fox (ASI), NASA | News | Comments

On October 8, 2014, active regions on the sun combined to look something like a jack-o-lantern’s face. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. The active regions appear brighter, because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona.
