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.

红外光波段的观测更雪上加霜让情况更加复杂难解，因为结果显示金牛座T星是一个多合星系统的成员，而和它相关的海德变光星云本身可能也藏有一个非常年轻的星体。

Over 400 light-years away, at the edge of a 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 .
