3D-Universe map

BOSTON — Astronomers have created the most complete 3-D map of our local universe, revealing new details about our place in the cosmos. The map shows all visible structures out to about 380 million light-years, which includes about 45,000 of our neighboring galaxies (the diameter of the Milky Way is about 100,000 light-years across). [See the new 3-D universe map image.]

The 2MASS Redshift Survey (2MRS) has catalogued more than 43,000 galaxies within 380 million light-years from Earth (z<0.09). In this projection, the plane of the Milky Way runs horizontally across the center of the image. 2MRS is notable for extending closer to the Galactic plane than previous surveys — a region that's generally obscured by dust.
