The Cone Nebula is a dark nebula located in the constellation of Monoceros, about 2,700 light-years away from Earth. It is part of a larger region known as the Rosette Nebula, which is a star-forming area rich in gas and dust. The Cone Nebula gets its name from its conical shape, which is created by the surrounding material being illuminated by nearby stars. This nebula is approximately 2.5 light-years long and is a site of active star formation. The dense regions within the nebula can collapse under gravity, leading to the birth of new stars. Observations of the Cone Nebula help astronomers understand the processes involved in stellar formation and the evolution of such regions in the universe.
