The LBN 777 is rarely imaged, also known as Vulture Head Nebula. This nebula is part of the Taurus Molecular Cloud. These giant molecular clouds consist of cosmic dust and molecular gas, with an average density of 100-1000 particles per cubic centimetre. These clouds are dark, not very dense and cold as well. The clouds can loose their gravitational balance quite easy due to some gravitational impact.
Taurus Molecular Cloud as a formation of a kind is one of the nearest to us, located about 400 light years away. Such a dense part of it LBN 777 – its external part lit by the surrounded stars (or even by the Milky Way itself)- can be observed as a very faint reflection nebula. Its more dense inner part is quite dark, cataloged as a dark nebula by E. E. Barnard (#207). This is the densest part of this nebula, (no starlight can permeate of it) where presumably new stars are born.
Very close, some 4.5 degrees away locates the famous Pleiades, which bright reflection cloud is part of the Taurus Molecular Cloud as well. The Eaglet Nebula is very faint, it can be observed only photographically.
