NASA is set to launch its newest mission on 26 June, the Interface Region Imaging Spectrograph, or IRIS. IRIS will show the lowest levels of the sun’s atmosphere, the interface region, in more detail than has even been observed before. This will help scientists understand how the energy moving through this area helps power the sun’s million-degree upper atmosphere, the corona. (Image Credit: NASA)
