Gigantic structure of galaxies

This image, obtained with the Subaru Telescope, operated by the National Astronomical Observatory of Japan was used by a team of astronomers, led by Masayuki Tanaka from the European Southern Observatory (ESO), to uncover a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us. This structure was confirmed by further observations made using ESO’s Very Large Telescope and Subaru. It is the first observation of such a prominent galaxy structure in the distant Universe, providing further insight into the cosmic web and how it formed.
