Here's an awesome omen that Halloween is fast approaching, courtesy of NASA's Solar Dynamics Observatory. These stunning solar activity images were captured on Oct. 8, 2014, and combine two sets of fall-hued wavelengths, creating a creepy, cosmic jack-o'-lantern.
Have a look ...
Here's the scoop from the Goddard Space Flight Center:
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. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.
