|Detail||：||Researchers from the National Astronomical Observatory of Japan, the University of Tokyo and other institutions have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in Hawai'i. Initial results from observations covering an area of 2.3 square degrees on the sky revealed nine large concentrations of dark matter, each the mass of a galaxy cluster. The image encompasses an area as large as ten full moons toward the constellation Cancer with fine resolution. These first results demonstrate that astronomers now have the techniques and tools to understand dark matter and dark energy. The next step is for the research team to expand the survey to cover a thousand square degrees on the sky, and thereby unravel the mystery of dark energy and the expansion of the universe.
