Australian, British and American astronomers have spent 10 years at the Anglo Australian Observatory meticulously charting hundreds of thousands of galaxies in our region of the universe.The work has led to the first accurate estimate of the parts of the universe that cannot be seen, giving us a street directory to the stars.Dr Heath Jones from the Anglo Australian Observatory says the map shows where galaxies are, in respect to each other, and to our own."Because of course we are looking into space, space is three dimensional and so really to look at this or we look at this map in a computer, we have to fly through the space between the galaxies, so we have to think of it as three dimensional space rather than a 2D roadmap," he said.
