A Southwest Research Institute-led team developed novel astrophysical processing techniques and applied them to extra-long exposures of the solar corona collected by NASA’s STEREO-A spacecraft (left) to bring this hard-to-image region into sharp focus (right). They created detailed images and movies that indicate that the Sun’s outer corona is more structured and dynamic than previously thought.
