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 conical interstellar dust pillar is pictured. The pillar is mostly
    brownish-red but surrounded by stars. Please see the explanation for
                         more detailed information.

   Explanation: Stars are forming in the gigantic dust pillar called the
   Cone Nebula. Cones, [4]pillars, and majestic [5]flowing shapes abound
   in [6]stellar nurseries where clouds of gas and dust are [7]sculpted by
   energetic winds from newborn stars. The [8]Cone Nebula, a well-known
   example, lies within the bright galactic star-forming region [9]NGC
   2264. The [10]featured image of the [11]Cone was captured recently
   combining 24-hours of exposure with a half-meter telescope at the
   [12]El Sauce Observatory in [13]Chile. Located about 2,500
   [14]light-years away toward the constellation of the Unicorn
   ([15]Monoceros), the [16]Cone Nebula's conical pillar [17]extends about
   7 light-years. The massive star [18]NGC 2264 IRS, is the [19]likely
   source of the wind sculpting the [20]Cone Nebula and lies off the top
   of the image. The [21]Cone Nebula's reddish veil is produced by glowing
   hydrogen gas.
