On April 25, 1998, the Transition Region and Coronal Explorer satellite captured this dramatic view of a 370,000-kilometer-wide solar prominence in ultraviolet light of three wavelengths: 171, 195 and 284 angstroms (shown, respectively, by blue, green and red colors). The huge luminous arches mark where concentrations of hot, ionized gas jut from the sun's surface. In "Stimulating Solar Prominences in the Laboratory," Paul M. Bellan describes his efforts to understand the nature of such gargantuan structures by studying miniature analogues to them.
