Hinode's View of Interface Region
This image from JAXA's Hinode mission shows the lower regions of the sun's atmosphere, the interface region, which a new mission called the Interface Region Imaging Spectrograph, or IRIS, will study in exquisite detail.

This image from JAXA’s Hinode mission shows the lower regions of the sun’s atmosphere, the interface region, which a new mission called the Interface Region Imaging Spectrograph, or IRIS, will study in exquisite detail. Where previous missions have been able to image material at only a few predetermined temperatures in this region, IRIS will observe a wide range of temperatures from 5000 Kelvins to 65,000 Kelvins (and up to 10 million Kelvins during solar flares). Its images will resolve structures down to 150 miles across. Credit: JAXA/Hinode› Link to associated news item
