| Comment | The Cone Nebula is an H II region in the constellation of Monoceros. The nebula is located about 2700 ly from Earth. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264. The faint nebula is approximately 7 ly long. IC 446 is a visible reflection nebula in the Unicorn constellation; it is one of the central regions of the association of massive stars known as Monoceros R1. It is a molecular cloud placed on the edge of a large complex of dark gas, cataloged as B37. The distance of the region is estimated at 2480 ly, on the outer edge of the Arm of Orion, near the inter-arm zone between it and the Arm of Perseus; the Monoceros R1 association counts some blue stars of spectral class B.(Text adapted from Wikipedia). |
