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: Jewels don't shine this bright -- only stars do. Like gems
   in a jewel box, though, the stars of [6]open cluster NGC 290 glitter in
   a [7]beautiful display of brightness and color. The photogenic cluster,
   [8]pictured here, was captured in 2006 by the orbiting [9]Hubble Space
   Telescope. Open clusters of [10]stars are younger, contain few stars,
   and contain a much higher fraction of blue stars than do [11]globular
   clusters of stars. NGC 290 lies about 200,000 [12]light-years distant
   in a neighboring galaxy called the [13]Small Cloud of Magellan (SMC).
   The [14]open cluster contains hundreds of stars and spans about 65
   light years across. [15]NGC 290 and other open clusters are good
   laboratories for studying how [16]stars of different masses evolve,
   since all the open cluster's stars were born at about the same time.
