km) long. Filaments consist of elongated clouds of cooler gases, tethered above the solar surface by powerful magnetic forces. They often exhibit instability and remain prone to erupting, although so far this one has remained intact. The images, taken in extreme ultraviolet light, actually show ionized helium at about 108,000 degrees F (60,000 degrees C). Less «
