The Cone Nebula is a complex region of hydrogen gas and interstellar dust approximately 2700 light years from Earth that interact to form a very tortured and twisted landscape. The Cone itself (left center) is formed by the interplay of ionized gas and a dust cloud that resemble the silhouette of a hooded Virgin with a halo clutching her child, hence the other common name for this feature, Madonna and Child. The brightest star in the image, 15 Monocerotis (right center), is part of the Christmas Tree Cluster and forms the base of the tree. A grouping of about a dozen bright stars to the left of 15 Monocerotis form the triangular shape of the Christmas tree, with the top of the tree being the bright star just right of the Cone itself. Below 15 Monocerotis is a region known to amateur astronomers as the Fox Fur Nebula. It and the area to the far right center are dust-choked regions giving the appearance of an animal’s fur coat.

This two-pane mosaic is the culmination of 18 hours of data collection in a collaborative effort between Howard Hedlund of Astro-Physics Inc. and Dave Jurasevich.
