WISPR is built with telescopes that create a solar eclipse type image by blocking the actual sun so its atmosphere, or corona, can be captured. These images show the Sun's emissions, including streamers, plumes, and the energetic coronal mass ejections that burst from the star.

According to Dr. Russell Howard, the NRL WISPR principal investigator, and a leading world authority on coronagraph telescopes, it's not just the pictures that are important—it's where that energy goes.
