                        Astronomy Picture of the Day

    Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   The featured image shows the surface of the Sun with a flowing texture
   in red light. Above the Sun's surface an unusual triangular prominence
      hovers. Please see the explanation for more detailed information.

   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.
