PERSEUS GIANT MOLECULAR CLOUD WITH STAR NURSERIES IC348 & NGC1333

NGC 1333 is a reflection nebula located in the northern constellation Perseus, positioned next to the southern constellation border with Taurus and Aries.[3] It was first discovered by German astronomer Eduard Schönfeld in 1855.[4] The nebula is visible as a hazy patch in a small telescope, while a larger aperture will show a pair of dark nebulae designated Barnard 1 and Barnard 2.[5] It is associated with a dark cloud L1450 (Barnard 205). Estimates of the distance to this nebula range from 980–1,140 ly (300–350 pc).[4]

This nebula is in the western part[4] of the Perseus molecular cloud and is a young region of very active star formation,[6] being one of the best-studied objects of its type.[4] It contains a fairly typical hierarchy of star clusters that are still embedded in the molecular cloud in which they formed,[7] which are split into two main sub-groups to the north and south. Most of the infrared emission is happening in the southern part of the nebula. A significant portion of the stars seen in the infrared are in the pre-main sequence stage of their evolution.[6]
