The Rosette Nebula


The Rosette Nebula

About the Rosette Nebula:
Located in the constellation of Monoceros (the Unicorn), the Rosette nebula is a prominent star formation region, glowing due to ultraviolet light from the young, hot, blue stars in the nebula. Massive stellar winds from these stars are clearing out the center of the nebula, creating the hole. The rich detail and structure in this object make the rosette one of the most photogenic objects in the night sky.

This image is sold as a poster in the catalog of the Astronomical Society of the Pacific, as well as at the Kitt Peak Visitor Center. It was featured as the Astronomy Picture of the Day on January 11th, 2000. It was also featured on the cover of the August 2000 cover of Astronomy magazine and inside the February 2001 issue of Sky & Telescope. It is also on display in the Explore the Universe exhibition in the Smithsonian National Air and Space Museum.

It is also on the cover of a few astronomy calendars, including the 2002 Astronomy magazine calendar. Observed by the Chandra telescope, this image shows a nice overlay of X-ray sources in the Rosette (Credit: X-ray: NASA/CXC/Penn State/L.Townsley et al.) My Rosette has also appeared in some rather unusual places (Credit: Jim Klemaszewski, Arizona State University).
