|Detail||：||This is the first version of a 3D map of the Universe from the FastSound Project, which is surveying galaxies in the Universe over nine billion light years away. Using Subaru Telescope's new Fiber Multi-Object Spectrograph (FMOS), the map includes 1,100 galaxies and shows the large-scale structure of the Universe about 4.7 billion years after the Big Bang. The area covers 2.5 times 3 degrees of the sky. The colors of the galaxies indicate their star formation rate, i.e., the total mass of stars produced in a galaxy every year. The gradation in background color represents the number density of galaxies; the underlying mass distribution (which is dominated by dark matter) would look like this if we could see it. The project is ongoing and will eventually include 5,000 galaxies over ten billion light years away.
