The famous young variable stellar object T Tauri, prototype to the class of pre-main-sequence objects which bears its name. T Tauri is actually a 0´´.6-separation binary star, unresolved in this image. (The objects very near the star just east of north and just west of south are filter glint artifacts, not infrared companions of T Tau.) The nebula to the west (NGC 1555) is reflected light from T Tauri.
