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 starfield is shown dominated by a purple and red nebula. Several
    dark dust pillars are visible that appear not unlike tadpoles. Please
             see the explanation for more detailed information.

   Explanation: [4]This cosmic skyscape features glowing gas and dark dust
   clouds alongside the young stars of [5]NGC 3572. A beautiful emission
   nebula and star cluster, it sails [6]far southern skies within the
   [7]nautical constellation Carina. Stars from NGC 3572 are toward top
   center in the telescopic frame that would measure about 100
   [8]light-years across at the cluster's estimated distance of 9,000
   light-years. The visible interstellar gas and dust, shown in [9]colors
   of the [10]Hubble palette, is part of the star cluster's natal
   [11]molecular cloud, itself cataloged as [12]Gum 37. Dense streamers of
   material within the nebula, eroded by stellar winds and radiation,
   clearly trail away from the energetic young stars. They are likely
   sites of ongoing star formation with shapes reminiscent of the
   [13]Tadpoles of IC 410 -- better known to northern skygazers. In the
   coming tens to hundreds of millions of years, gas and stars in the
   cluster will be dispersed though, by [14]gravitational tides and by
   violent [15]supernova explosions that end the short lives of the
   massive cluster stars.
