Eruptive Chaos


A swirling mass of plasma churned above the Sun for almost two days before it finally erupted (Feb. 25-26, 2013). Some of the matter was cooler than surrounding matter so it appears quite a bit darker than the material swirling behind it. The images are a combination of two wavelengths of extreme ultraviolet light. The darker material was more easily seen in the 193 Angstrom wavelength; the broader and lighter mass was more easily seen in the 304 Angstrom wavelength. By combining them and adding some contrast and color shift, we get the best of both worlds.
