Hi all,
Sh2-239 is a very active star-forming place. It is an object where many Herbig-Haro objects can be found and, in infra-red images, it shows many Young Stellar Objects (YSOs). You can find a more detailed explanation and the image at the link below. This image belongs to the recently compilated collection of the 87 scientifically interesting objects posted recently.
Enjoy!
