LDN 1251, about a 1000 lightyears from Earth, is a low mass molecular cloud in the constellation of Cepheus.

This dark nebula is a cloud that became opaque because of its internal dust grains. The form of such dark clouds is very irregular: they have no clearly defined outer boundaries and sometimes take on convoluted serpentine shapes. The largest dark nebulae are visible to the naked eye, appearing as dark patches against the brighter background of the Milky Way. Dark nebulae are often associated with newborn stars.

In addition to the dark nebula, this image also shows a handful of PGC galaxies that shine far in the background behind LDN 1251.
