NGC 1333 is a reflection nebula visible in the constellation Perseus and located at a distance of about 766 light-years from Earth. It is the most active star-forming region in the Perseus molecular cloud. The term NGC 1333 is also used to denote the young stellar cluster that illuminates this region of gas and dust; the approximately 150 stars that compose it present low to intermediate masses and their median age is of about 1 million years. Most of these stars are obscured by the dark dusty cloud from which they formed, known as Barnard 205.
