A stunning false-color composite image of the Sun from the SOHO spacecraft's EIT instrument, capturing active regions, plasma loops, and a prominence. The image combines three extreme ultraviolet wavelengths, representing different temperatures in the Sun's upper atmosphere (red: 2 million, green: 1.5 million, blue: 1 million degrees Celsius). Taken on December 22nd, 2002, at the winter solstice.
