The combination of an ultraviolet telescope and spectrograph is yielding unprecedented images of the Sun's lower atmosphere. The pictures this month from NASA's Interface Region Imaging Spectrograph, or IRIS, "are going to help us understand how the Sun's lower atmosphere might power a host of events around the Sun. Anytime you look at something in more detail than has ever been seen before, it opens up new doors to understanding," said Adrian Daw, the mission scientist for IRIS at NASA's Goddard Space Flight Center.
