Unicorns and roses are usually the stuff of fairy tales, but a new cosmic image taken by NASA's Wide-field Infrared Explorer (WISE) shows the Rosette nebula located within the constellation Monoceros, or the Unicorn. This flower-shaped nebula, also known by the less romantic name NGC 2237, is a huge star-forming cloud of dust and gas in our Milky Way galaxy. Estimates of the nebula's distance vary from 4,500 to 5,000 light-years away. At the center of the flower is a cluster of young stars...

Its neighbor, Puppis, on the other hand, boasts no bright stars, and is difficult at best for even seasoned observers to identify. Stellar beacons notwithstanding, both of these constellations are rich in open clusters, as they lie along the winter Milky Way. Several...

Open Cluster -- An open cluster is a group of star formed from a molecular cloud, the illuminated parts of which we see as one or more nebulae. They are also called galactic clusters since they exist within the galaxy. All the stars in an open cluster have more or less the same age and the same chemical composition, so any difference between them is solely due to their mass. Most open clusters are dominated by their O-type and B-type giant blue stars, which are very luminous but...
