These high resolution images of space scenes are matted to perfection on quality card-stock board and feature a description of the image on back. This is a close-up shot of what's called an expanding solar prominence, seen in extreme ultraviolet light, of our very own sun. The light we are seeing in this observation is generated by plasma heated to around 50,000 Kelvin (twice as hot as a bolt of lightning). A solar prominence is a looped structure of hot plasma, wrapped in magnetic fields from the sun's "surface" (or the photosphere), projecting high into the solar atmosphere (the sun's corona).
