   Explanation: [5]An unassuming region in the constellation Taurus holds
   these dark and dusty nebulae. Scattered through the scene, stars in
   multiple star systems are forming within their natal [6]Taurus
   molecular cloud complex some 450 light-years away. Millions of years
   [7]young and still going through stellar adolescence, [8]the stars are
   variable in brightness and in the [9]late phases of their gravitational
   collapse. Known as [10]T-Tauri class stars they tend to be faint and
   take on a yellowish hue in the image. One of the brightest T-Tauri
   stars in Taurus, V773 (aka HD283447) is near the center of the
   telescopic frame that spans over 1 degree. Toward the top is the dense,
   [11]dark marking on the sky cataloged as Barnard 209.
