                        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 dominated by a multi-colored figure 8 in the middle,
   titled on a diagonal. The outsides of the nebula appear light colored,
   while the inside shows complex structure tinted red and purple. Please
             see the explanation for more detailed information.

   Explanation: What happens when a star runs out of nuclear fuel? For
   stars like our Sun, the center condenses into a white dwarf while the
   outer atmosphere is expelled into space to appear as a planetary
   nebula. The expelled outer atmosphere of planetary nebula NGC 1514
   appears to be a jumble of bubbles -- when seen in visible light. But
   the view from the James Webb Space Telescope in infrared, as featured
   here, confirms a different story: in this light the nebula shows a
   distinct hourglass shape, which is interpreted as a cylinder seen along
   a diagonal. If you look closely at the center of the nebula, you can
   also see a bright central star that is part of a binary system. More
   observations might better reveal how this nebula is evolving and how
   the central stars are working together to produce the interesting
   cylinder and bubbles observed.
