Rosette Nebula , Paula Zwierzynski

Rosette Nebula

Located near the constellation Monoceros, the Rosette Nebula was named for its beautiful rosette shape and reddish hue. The Rosette Nebula’s reddish tint comes from a dominant number of hydrogen atoms. The winds and energetic light that nearby massive stars produce are eroding the dust and gas globules that form this nebula, known under the catalogued title NGC 2244. It is estimated that, if given enough time, stars and planets could plausibly form from the Rosette Nebula’s molecular clouds.

The Rosette Nebula is located 4,500 light years from our own galaxy, and it stretches nearly 130 light years in distance. The nebula itself is visible because of radiation that is excited by bright young stars found within its gases. The measurements as found in this photo correspond 14 minutes to 18 light years. However, the photo taken here likely does not span the entire distance of the Rosette Nebula.
