The Perseus molecular cloud is a giant molecular cloud in the constellation of Perseus and contains over 10,000 solar masses of gas and dust. NGC 1333 (somewhere left) is one of the brighter parts of the molecular cloud, illuminated by a young star about 1,000 light-years from Earth. This photo shows the large amount of dust in the sky around NGC 1333, which is the raw material for the formation of new stars in our galaxy.
