This ultraviolet-wavelength image shows a hugh solar prominence on September 14, 1999. Solar prominences are large, arch-shaped filaments of relatively cool, dense plasma that are suspended above the surface of the sun. Sometimes solar prominences can erupt, allowing matter to escape the Sun's atmosphere. The features visible in this image trace the Sun's magnetic field, with hotter regions appearing light and cooler regions appearing dark.
