The new 3D map of the universe

Astronomers at the University of Portsmouth, England, have created the most comprehensive map 3D map of the universe. The map, which covers 95% of the sky, and was submitted to 218esimo conference of the American Astronomical Society, shows all visible structures within 380 million light years from Earth, including about 45,000 nearby galaxies to our (the diameter of the Milky Way is about 100 thousand light-years).
The map was assembled using data from the Two-Micron All Sky Survey Redshift Survey. It took 10 years to perform a full scan of the night sky using near infrared light rays, and used two ground-based telescopes, the Fred Lawrence Whipple Observatory on Mount Hopkins in Arizona and the Cerro Tololo Inter-American Observatory in Chile .
