A
magnetic filament of solar material erupted on the sun in late September,
breaking the quiet conditions in a spectacular fashion. The 200,000 mile long
filament ripped 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.
