The Rosette Nebula, also known as NGC 2237, is a large emission nebula located in the constellation Monoceros (the Unicorn). It is approximately 4,500 to 5,000 light-years away from Earth and is part of a larger molecular cloud complex. The nebula has a diameter of about 50 light-years and is notable for its strikingly beautiful and intricate structure, which resembles a rose—hence its name.
