Scientists have unveiled the largest map of the universe ever created. Stretching across a tiny sliver of space and almost all cosmic time, it includes almost 800,000 galaxies imaged across the universe. Some are so far away that they appear as they existed in the infant universe, about 13 billion years ago.
The map, released Thursday (June 5) by scientists at the Cosmic Evolution Survey collaboration , covers a 0.54-degree-squared arc of the sky, or about three times as much space as the moon takes up when viewed from Earth.
