A Triangular Prominence Hovers Over the Sun
Explanation: Why is there a triangle hovering over the Sun? Although the shape is unusual, the type of structure is not: it is part of an evolving
solar prominence. Looping magnetic fields on the
Sun channel the flow of energetic particles, sometimes holding glowing gaseous structures aloft for months. A
prominence glows brightly because it contains particularly hot, dense, or opaque solar
plasma. The
surprising triangular structure occurred last week. Larger than our Earth, the
iconic prominence was imaged by several solar photographers and
documented by NASA's
Solar Dynamic Observatory to form and violently dissipate in about a day. The
featured image was captured in a color of
red light emitted strongly by
hydrogen. Below,
solar fibrils carpet the
Sun's chromosphere, while the background sky is so faint in comparison that no stars are visible. Our Sun's surface has been
quite active this year.
