A T Tauri star is a young stellar object that is about to collapse to become a main sequence star similar to the Sun. What is special about V1331 Cygni is that we are looking almost directly at one of its poles. Usually the view of young stars is obscured by a surrounding disk of dust. The jet emanating from the pole blows dust away and reveals the reflection nebula surrounding the star. [409] The distance is around 597 pc [145]
