|What does the universe nearby look like?
This plot shows nearly 50,000 galaxies in the nearby universe detected by the
Two Micron All Sky Survey
(2MASS) in infrared
The resulting image is anincredible tapestry of galaxies that
provides limits on how the universe formed and evolved.
The dark band across
the image center is blocked by dust in the
plane of our own
Milky Way Galaxy.
Away from the Galactic plane, however, each dot represents a
coded to indicate distance.
Bluer dots represent the nearer galaxies in the
while redder dots indicating the more
distant survey galaxies that lie at a
redshift near 0.1.
Named structures are annotated around the edges.
Many galaxies are
gravitationally bound together to form
which themselves are loosely bound into
which in turn are sometimes seen to
align over even larger scale structures.
