The term "The Local Group" was introduced by Edwin Hubble in Chapter VI of his 1936 book The Realm of the Nebulae. [11] There, he described it as "a typical small group of nebulae which is isolated in the general field" and delineated, by decreasing luminosity, its members to be M31, Milky Way, M33, Large Magellanic Cloud, Small Magellanic Cloud, M32, NGC 205, NGC 6822, NGC 185, IC 1613 and ...
Composite image showing young stars in and around molecular cloud Cepheus B.. This is a list of star-forming regions located in the Milky Way Galaxy and in the Local Group.Star formation occurs in molecular clouds which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions.

The Local Sheet in astronomy is a nearby extragalactic region of space where the Milky Way, the members of the Local Group and other galaxies share a similar peculiar velocity. [2] This region lies within a radius of about 7 Mpc (23 Mly ), [ 3 ] 0.46 Mpc (1.5 Mly) thick, [ 1 ] and galaxies beyond that distance show markedly different velocities ...

A local community has been defined as a group of interacting people living in a common location. The word is often used to refer to a group that is organized around common values and is attributed with social cohesion within a shared geographical location, generally in social units larger than a household.
A reference group can be either from a membership group or non-membership group. An example of a reference group being used would be the determination of affluence. An individual in the U.S. with an annual income of $80,000, may consider themself affluent if they compare themself to those in the middle of the income strata, who earn roughly ...
OPPOSE "Local Group" is an established astronomical term, with a clear definition of its member galaxies. A list is nice, but only as an additional overview, and might describe either more or less galaxies (depending on the range) than the Local Group. --84.178.157.201 11:19, 18 January 2006 (UTC) OPPOSE I agree, it should remain separate.
