Starry Starry Sky
Above Us Only Sky
Each dot in the picture above indicates the position of a galaxy.
The image covers about 1/20th of the sky, a slice of the universe 6 billion light-years wide (thus we see some of these galaxies 6 billion years into the past), 4.5 billion light-years high, and 500 million light-years thick.
July 2016 - The largest three-dimensional map of our universe so far. It’s a map of 1.2 million galaxies over a quarter of the sky and over a volume of space of 650 cubic billion light-years.
