The Sun in Ultraviolet Light This false-color image was made in ultraviolet light by the Solar Dynamics Observatory. A very long filament is seen cutting across the Sun’s southern hemisphere; it is longer than the distance from Earth to the Moon! The filament is confined by a strong magnetic field, and above the filament is a bright sunspot group.
