APOD 3.7

The Rosette Nebula, pictured above, is on of the most beautiful celestial objects I have ever seen. This image of it was taken using multiple long exposures of very specific colors of Sulfur (red), Hydrogen (green), and Oxygen (blue). The combination of the pictures gives us a magnificent blend of purples, oranges, and yellows. The Rosette Nebula is relatively young, being only a few million years old. It is measured to be over 50 light years across and about 4,500 light-years away in the constellation Monoceros (Unicorn). This APOD stuck out to me, not only because of its beauty, but on today's Constellation Quiz, Monoceros was one of the constellations we had to know.
