The View from Stereo Ahead

On December 22, the Sun reached its southernmost point in Earth's sky, marking the winter solstice. The STEREO Ahead spacecraft captured these images of the Sun on December 4, its first day of imaging. The false-color views highlight different temperatures in the Sun's upper atmosphere, with yellow showing 2 million Kelvin and red showing 1.5 million Kelvin.
