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.

   Explanation: Sometimes, the surface of our Sun seems to dance. In the
   middle of 2012, for example, NASA's Sun-orbiting [6]Solar Dynamic
   Observatory spacecraft imaged an [7]impressive prominence that seemed
   to perform a [8]running dive roll like an acrobatic dancer. The
   dramatic explosion was [9]captured in [10]ultraviolet light in the
   [11]featured time-lapse video covering about three hours. A looping
   [12]magnetic field directed the flow of hot [13]plasma on the [14]Sun.
   The scale of the [15]dancing prominence is huge -- the entire [16]Earth
   would easily fit under the flowing [17]arch of hot gas. A quiescent
   [18]prominence typically lasts about a month and may erupt in a
   [19]Coronal Mass Ejection (CME), [20]expelling hot gas into the
   [21]Solar System. The energy mechanism that creates a [22]solar
   prominence is still a topic of [23]research. Like in 2012, this year
   the Sun's surface is again [24]quite active and features many
   [25]filaments and prominences.
