The Luminous Galaxies chart is the biggest ever 3D map of the universe.

Our Milky Way galaxy (blue) is seen here 
absorbing its galactic neighbour, Sagittarius, (red trail) in 2003; 
the colour of a galaxy indicates its age

These images from the ongoing Sloan Digital Sky Survey III 
show the northern (left) and southern hemispheres of the Earth,
