NASA telescope snaps best photos yet of sun's atmosphere

NASA telescope snaps best photos yet of sun's atmosphere

A NASA telescope snapped the best-ever images of the sun's million-degree outer atmosphere during a brief spaceflight this month, agency officials say.
The High Resolution Coronal Imager, or Hi-C for short, captured 165 stunning pictures of the sun's corona during a 10-minute suborbital flight on July 11. The telescope focused its gaze on a large sunspot, a temporary blemish on the sun that appears dark because it is cooler than the rest of the solar surface.
