   Explanation: The cosmic brush of star formation composed [5]this
   interstellar canvas of emission, dust, and dark nebulae. A 5 degree
   wide telescopic mosaic, it frames a region found north of bright star
   Aldebaran on the sky, at an inner wall of [6]the local bubble along the
   [7]Taurus molecular cloud. At lower left, emission cataloged as
   [8]Sh2-239 shows signs of embedded young stellar objects. The region's
   Herbig-Haro objects, nebulosities associated with newly born stars, are
   marked by tell-tale reddish jets of shocked hydrogen gas. Above and
   right T Tauri, the prototype of the class of [9]T Tauri variable stars,
   is next to a yellowish nebula historically known as Hind's Variable
   Nebula ([10]NGC 1555). T Tauri stars are now generally recognized as
   young, less than a few million years old, sun-like stars still in the
   early [11]stages of formation.
