   Explanation: The [7]massive stars of NGC 346 are short lived, but very
   [8]energetic. The star cluster is embedded in the largest star forming
   region in the [9]Small Magellanic Cloud, some 210,000 light-years
   distant. Their winds and radiation sweep out an interstellar cavern in
   the gas and dust cloud about 200 light-years across, [10]triggering
   star formation and sculpting the region's dense inner edge. Cataloged
   as N66, the star forming region also appears to contain a large
   population of [11]infant stars. A mere 3 to 5 million years old and not
   yet [12]burning hydrogen in their cores, the [13]infant stars are
   strewn about the embedded star cluster. In this false-color [14]Hubble
   Space Telescope image, visible and near-infrared light are seen as blue
   and green, while light from atomic hydrogen emission is red.
