This combination of images made available by NASA's Goddard Space Flight Center on Thursday, July 25, 2013 shows a comparison between the higher resolution provided by the new ISIS (Interface Region Imaging Spectrograph), right, and the SDO (Solar Dynamics Observatory) spacecraft. Launched in June 2013, NASA's IRIS has a scheduled mission of two years. Scientists say the observations will help shed light on the sun's impact on Earth. (AP Photo/NASA, Goddard Space Flight Center)
