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]A large filament on the upper left is seen lifting away from the
    Sun, pictured on the lower right. Please see the explanation for more
                            detailed information.

   Explanation: What's happened to our Sun? Nothing very unusual -- it
   just [6]threw a filament. Toward the middle of 2012, a [7]long standing
   [8]solar filament suddenly erupted into space, producing an energetic
   [9]coronal mass ejection (CME). [10]The filament had been held up for
   days by the Sun's ever changing [11]magnetic field and the timing of
   the eruption was [12]unexpected. [13]Watched closely by the
   Sun-orbiting Solar Dynamics Observatory, the resulting [14]explosion
   [15]shot electrons and ions into the Solar System, some of which
   arrived at Earth three days later and impacted Earth's
   [16]magnetosphere, causing visible [17]auroras. Loops of plasma
   surrounding the [18]active region can be seen above the erupting
   filament in [19]the featured [20]ultraviolet image. Our Sun is nearing
   the [21]most active time in its [22]11-year cycle, creating many
   [23]coronal holes that allow for the ejection of [24]charged particles
   into space. As before, these charged particles can [25]create auroras.
