Glossary term: Solar Prominence

Description: Solar prominences (sometimes referred to as filaments) are loops of plasma that form due to the magnetic fields around the Sun. These are temporary but may persist for weeks or months and can often be photographed during solar eclipses. A typical prominence extends over many thousands of kilometers (km); the largest on record was estimated at over 800,000 km long, roughly a solar radius. As with many solar phenomena, other stars are also thought to exhibit prominences.
