Astronomy Picture of the Day

   [1]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.

         Video Credit: [3]Ralf Burkart; [4]h/t Maciej Libert ([5]AG)

   Explanation: Watch for three things in this unusual eclipse video.
   First, watch for a big dark circle to approach from the right to
   [6]block out more and more of the Sun. This dark circle is the [7]Moon,
   and the video was made primarily to capture this [8]partial solar
   eclipse last week. Next, watch a [9]large solar prominence hover and
   shimmer over the [10]Sun's edge. A close look will show that part of it
   is actually [11]falling back to the [12]Sun. The prominence is made of
   hot [13]plasma that is temporarily held aloft by the [14]Sun's changing
   magnetic field. Finally, watch the Sun's edge [15]waver. What is
   [16]wavering is a dynamic carpet of [17]hot gas tubes rising and
   falling through the [18]Sun's chromosphere -- tubes known as
   [19]spicules. The entire 4-second [20]time-lapse video covers a time of
   about ten minutes, although the Sun itself is expected to [21]last
   another 5 billion years.
