Giant fountains of fast-moving, multimillion-degree gas in the outermost atmosphere of the Sun. The gas fountains emanating from the surface form arches (some more than 300,000 miles high) and are heated and rise while flowing along the solar magnetic field. The gas then cools and crashes back to the surface at more than 60 miles per second. This image is a false color picture of ultraviolet light emitted by the hot gas that comprises the coronal loops.

Magnetic filament of solar material erupting as a 200,000-mile-long filament rips through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields.

The sun is pictured shortly before releasing an X-class flare. This image combines two sets of observations of the sun - light in the 171 Angstrom wavelength, which shows off giant loops of solar material overlying the middle of the sun over the region where the flare originated and a magnetogram, which highlights magnetic fields on the sun.
