Image of the Sun showing an exceptionally long solar filament, a dark streak of hot gas held aloft by the Sun's magnetic field, extending across a significant portion of the Sun's surface. Captured in hydrogen light, highlighting the chromosphere. This filament is longer than the Sun's radius, measuring over 700,000 kilometers.
