The Rosette Nebula is a huge star-forming region spanning 100 lightyears across and located 5,000 lightyears away.

It can be seen in the Monoceros constellation in the winter months, located between stars Betelgeuse in the constellation Orion.

At the center of the nebula is NGC 2244, a group of stars that form a gravitationally bound open star cluster thought to be about 4 million years old.
