Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only four million years ago and emit light and wind that define the nebula's appearance today. High energy light from the bright young stars of NGC 2244 ionizes the surrounding hydrogen gas clouds to create the red emission nebula appearance. The hot wind of particles that streams away from the cluster stars contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. NGC 2244 measures about 50 light-years across, lies about 4500 light-years away, and is visible with binoculars towards the constellation of Monoceros.

It's in the direction of the constellation Monoceros (Unicorn).
Using binoculars or a telescope,look slightly south of an imaginary line between star Procyon and star Betelgeuse, about 2/3 of the way toward Betelgeuse.
In Mid March, in the mid-latitudes of the Northern Hemisphere, you'll need to look after full dark but before 10:30 PM.
BTW, light pollution WILL blot out your view of the nebula.
