Emission nebula including Herbig-Haro objects
The emission nebula Sh2-239 is embedded in LDN 1551, a dark nebula
region near the southern end of the Taurus molecular cloud complex
some 450 light-years distant.
Many signs of embedded young stellar objects driving dynamic
outflows into the surrounding medium are visible.
Estimates indicate that the star forming LDN 1551 region contains
a total amount of material equivalent to about 50 times the mass of the Sun.
