Christmas Tree Cluster Poster


This wide-field image of the Christmas Tree Cluster was taken at the National Science Foundation’s 0.9-meter telescope on Kitt Peak with the NOAO Mosaic CCD camera. Also known as NGC2264, it is an open cluster of stars embedded in a diffuse nebula. It is located in the constellation of Monoceros, the Unicorn. The image also contains two famous nebula. At the top center of the image is the Cone Nebula, and to the lower right is the Fox Fur Nebula. The bright star just below the center of the image is known as S Mon. The gentle arcs in orange and blue near the center of the image are Herbig Haro objects, jets of gas from protostars embedded in the nebula. In this image north is down and east is to the left. This image was created by combining emission-line images in Hydrogen-alpha (red-orange), Oxygen [O III] (light blue) and Sulfur [S II] (blue-violet).
