IC 348 (also known as IC 1985) is a 2 million year old open star cluster surrounded by the reflection nebula vdB 19 (also known as Cederblad 20), located 890 light-years away from Earth in the constellation of Perseus.
The light from the roughly 400 stars in the cluster is scattered by clouds of dust in the star-forming region, producing the reflection nebula. The cluster’s brightest members are hot, bright bluish Main Sequence stars, but some stars are still in the process of formation, so star formation is an ongoing process in the region.

IC 348 and the dark nebulas Barnard (B) 3 and 4 are embedded in the star-forming region called the Perseus OB2 molecular cloud.
