About this object

Sharpless 2-239 is a dusty star forming region within the Taurus molecular cloud that stretches for nearly 3 light years. The brighter nebula right of center is Sh2-239, part of the broader dark nebula LDN 1551 surrounding it. The dark nebula surrounding Sh2-239 contains material equivalent to 50 times the mass of the sun. Within the brighter cloud are dozens of protostars causing the nebula to glow. Also within the nebula are several Herbig-Haro objects, typical of star forming regions.
