Radiation from young stars in NGC2237 makes the nebula shine by exciting its atoms to emit radiation. The dark nebula, consisting of cooler gases and dust, is highlighted against this glowing background.  This picture is a small 22’x16’ arc minute view of a portion of the Rosette Nebula located 5,200 light years away from our home in the Constellation Monoceros.
