Comments: The orange star centered in this view is T Tauri, prototype of the class of T Tauri variable stars. Nearby it is a dusty yellow cosmic cloud historically known as Hind's Variable Nebula (NGC 1555/1554). 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. 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 (Ref). The red star in the right portion of this image is V1100 Tauri, a spectral class M variable star. Many dusty nebulae are seen in the region, some of which have not been cataloged. This image was a challenge to take and process since it was shot through the nearby night skiing lights of Pebble Creek Ski Area.
