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: Planetary nebula [5]Jones-Emberson 1 is the [6]death
   shroud of a dying Sun-like star. It lies some 1,600 light-years from
   Earth toward the [7]sharp-eyed constellation Lynx. About 4 light-years
   across, the expanding remnant of the dying star's atmosphere was
   [8]shrugged off into interstellar space, as the star's central supply
   of hydrogen and then helium for fusion was depleted after billions of
   years. Visible near the center of the planetary nebula is what remains
   of the stellar core, a blue-hot [9]white dwarf star. Also known as PK
   164 +31.1, the nebula is faint and very difficult to glimpse at a
   telescope's eyepiece. [10]But this deep image combining over 12 hours
   of exposure time does show it off in exceptional detail. Stars within
   our own Milky Way galaxy as well as background galaxies across the
   universe are scattered through the clear field of view. [11]Ephemeral
   on the cosmic stage, Jones-Emberson 1 will fade away over the next few
   thousand years. Its hot, central white dwarf star will take
   [12]billions of years to cool.
