      Explanation: The star with an orange tint near top center in this dusty   
      telescopic frame is T Tauri, prototype of the class of T Tauri variable   
      stars. Next to it (right) is a yellow cosmic cloud historically known   
      as Hind's Variable Nebula (NGC 1555). About 650 light-years away, at   
      the boundary of the local bubble and the Taurus molecular cloud, both   
      star and nebula are seen to vary significantly in brightness but not   
      necessarily at the same time, adding to the mystery of the intriguing   
      region. T Tauri stars are now generally recognized as young (less than   
      a few million years old), sun-like stars still in the early stages of   
      formation. To further complicate the picture, infrared observations   
      indicate that T Tauri itself is part of a multiple system and suggest   
      that the associated Hind's Nebula may also contain a very young stellar   
      object. The well-composed image spans about 8 light-years at the   
      estimated distance of T Tauri.
