                        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.

    A starfield is shown with a large spherical nebula in the center. The
       nebula shows a great deal of internal structure. Please see the
                 explanation for more detailed information.

   Explanation: Some stars explode in slow motion. Rare, massive
   Wolf-Rayet stars are so tumultuous and hot that they are slowly
   disintegrating right before our telescopes. Glowing gas globs each
   typically over 30 times more massive than the Earth are being expelled
   by violent stellar winds. Wolf-Rayet star WR 124, visible near the
   featured image center and spanning six light years across, is thus
   creating the surrounding nebula known as M1-67. Details of why this
   star has been slowly blowing itself apart over the past 20,000 years
   remains a topic of research. WR 124 lies 15,000 light-years away
   towards the constellation of the Arrow (Sagitta). The fate of any given
   Wolf-Rayet star likely depends on how massive it is, but many are
   thought to end their lives with spectacular explosions such as
   supernovas or gamma-ray bursts.
