APOD 3.5

February 14th, 2011.                                     The Rosette Nebula


How fitting was it that the Rosette Nebula happened to be an APOD of the day during the week in which we learned about the constellation Monoceros in class.  Also known as NGC 2237, the Rosette Nebula is an Emission Nebula containing an open cluster of bright stars at the center known as NGC 2244.  It is believed that these stars formed four from Nebular Material.  Currently, these stars' stellar winds are clearing a hole at the center of the galaxy, insulating it by the dust and gas that we learned make up the interstellar medium.  Ultraviolet light coming off as radiation from the cluster of stars in the center of the Nebula cause the glowing effect that makes the Nebula look so interesting and intriguing.  The Rosette Nebula is located about 5,000 Light-Years away and spans for a distance of 1,000 Light-Years across.
