Christmas Tree

There are several cosmic objects in this wide angle image, including Cone Nebula (top), the Christmas Tree cluster of stars (below the Cone), and Fox Fur Nebula (surrounding the Christmas Tree cluster). The large star in the top center of the field is S Mon, a young, highly energetic star whose light and hot matter is causing the surrounding interstellar dust to form the odd conical and stretched shapes, including the fur-like folds.
