Description

LDN1251 is an elongated molecular cloud on the eastern edge of the Cepheus molecular cloud complex, an extended region containing giant molecular clouds and very young and bright blue stars associations. It is one of the closest star-forming regions to us and it appears considerably obscured, especially as regards the OB associations, by extensive dark nebulae placed along our line of sight. The comet shape of LDN1251 suggests that it is in interaction with the large super-bubble caused by the explosion of a supernova. Its distance from us has been determined in various ways and different emission lines have been detected, such as the 13CO, the SiO, NH3, HCN and others. Two small galaxies are visible in the field, PGC69472 e PGC166755, just near the edge of the cloud body, along with numerous Herbig-Haro objects, visible as small patches of nebulosity associated with newly born stars.
