The Perseus Molecular Cloud is a large region of gas and dust located in the constellation Perseus. It is part of a larger complex of molecular clouds and is known for being a site of active star formation. The cloud contains several young stars and protostars, which are still in the process of forming. This molecular cloud is approximately 600 light-years away from Earth and spans about 100 light-years across. It is rich in molecules such as hydrogen and carbon monoxide, making it an important area for astronomers studying the processes of star and planet formation in the universe.
