								The Rosette Nebula, aka NGC 2237, is located in the constellation Monoceros, spanning a diameter of 100 lightyears, and seen at a distance of 5000 lightyears. The open cluster of stars in the central portion of the nebula is known as NGC 2244, and energy from these stars causes the surrounding hydrogen gas to glow.  The so-called stellar winds are also responsible for clearing a hole in the center of the nebula.
