An observation showing that the dark matter in the universe is divided in the form of a network of dense (white) and empty (black) regions. The largest white areas are the size of the full moon in the sky. Photo: van Weerbeek, Hymans and CFHTLenS partners

Astronomers measured the concentration of dark matter about 6 billion years ago
