Sh2-239 is a minor and compact emission nebula positioned at about 4 degrees NNW from the Aldebaran, alpha Tau. We can find out the nebula in the Hyades apparently, actually the nebula is three times farther than the Hyades.
We can observe the Sh2-239 as an emitted part of the dark nebula of LDN1551 with a T Tauri-tyed embryo star. The brightest region of Sh2-239 is catalogued as the Herbig-Haro object HH102, which has the active jet-structure of the inter-stellar gaseous matter.
