Mapping the Early/Distant Universe

Wired Science on astronomers’ efforts to map the distant (and young) universe. “Previous versions plotted the locations of galaxies within 7 billion light-years of Earth. The new version, however, charts clouds of hydrogen in a swath between 10 billion and 12 billion light-years away — farther in distance and deeper in time than any 3-D map before it.” Via @jpmaps.
