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.

     [2]The edge of the Sun is shown sporting a large gaseous prominence
   that looks like a science-fiction alien. Please see the explanation for
                         more detailed information.

   Explanation: The monsters that live on the Sun are not like us. They
   are larger than the [5]Earth and made of gas hotter than in any
   [6]teapot. They have no eyes, but at times, [7]many tentacles. They
   [8]float. Usually, they slowly change shape and just [9]fade back onto
   the Sun over about a month. Sometimes, though, they [10]suddenly
   explode and [11]unleash energetic particles into the Solar System that
   can attack the Earth.  Pictured is a [12]huge solar prominence imaged
   almost two weeks ago in the [13]light of hydrogen. Captured by a small
   telescope in [14]Gilbert, [15]Arizona, [16]USA, the
   [17]monster[18]esque plume of gas was held aloft by the ever-present
   but [19]ever-changing magnetic field near the surface of the Sun. Our
   [20]active Sun continues to show an [21]unusually high number of
   [22]prominences, [23]filaments, [24]sunspots, and [25]large active
   regions as [26]solar maximum approaches in 2025.
