The Rosette Nebula, NGC2237-39, 46, Monoceros

A wider view of this appropriately named nebula surrounding NGC2244, a young star cluster of ~15 stars including the yellow 6th magnitude star 12 Mon, that formed out of the nebula. Clearly evident is the cavity created by the stellar winds of the hot, young stars. Visible, too, are numerous dark dusty regions and globules suggestive that star formation is on-going. With an estimated mass of 10,000 solar masses the nebula has plenty of material left for star formation in the future; distance 2,600 ly. Here's a closer view.
