The Ara OB1A , Scorpius OB1 - west, Scorpius OB1 - east and Eagle/Omega regions are massive molecular cloud and star formation areas located immediately across a large gap inwards from our local region of the Milky Way. These areas are often considered to be part of the Sagittarius Arm of the Milky Way, although some astronomers argue that these molecular clouds are not part of an arm as they do not form an arc-like density wave. (See articles by Anna Mel'nik here and here for more details.)
Further beyond these areas is the Milky Way's nucleus at a distance of about 8000 parsecs.
