The Ghostly Remnants of Galaxy Interactions Uncovered in a Nearby Galaxy Group
Deep and ultra wide field of view image from Hyper Suprime-Cam mounted on the Subaru Telescope including a large spiral galaxy M81, M82, dwarf galaxy Holmberg IX and NGC 3077. The research team's analysis revealed the trace of its past interactions with the neighboring galaxies. It is exciting to see the evidence of the hierarchical galaxy assembly process at this distance beyond the Local Group of galaxies.

Dark Matter Map Begins to Reveal the Universe's Early History
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.

First Version of a 3D Map of Universe from the FastSound Project
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.

Direct Imaging Discovery of a Second Jupiter
What is an exoplanet and why is direct imaging of a "second Jupiter" around the Sun-like star GJ 504 so significant? This movie describes the answers to these questions. Exoplanets are planets orbiting stars other than our Sun, outside of our Solar System. Indirect observation techniques like radial velocity variation or planetary transits have been the main way that the 890 exoplanets reported thus far have been discovered. In contrast, only a dozen planets with a location similar in scale to that of the Solar System have been discovered, and the Subaru Telescope's direct imaging of GJ 504 b now joins the list. The discovery is part of the SEEDS (Strategic Explorations of Exoplanets and Disks with Subaru) Project, an international project approved by the National Astronomical Observatory of Japan (NAOJ); begun in 2009, it continues to probe this new frontier as part of a five-year direct imaging survey of exoplanets and disks around a targeted total of 500 stars.

Closeups of the Andromeda Galaxy Captured by Subaru Telescope's Hyper Suprime-Cam
View closeups of this stunning image of M31, the Andromeda Galaxy, taken with Subaru Telescope's new prime-focus instrument, Hyper Suprime-Cam (HSC). HSC's first beautiful image of M31 answers the question: Does HSC really deliver what it promises in terms of image quality? It displays a resounding "yes" by demonstrating the sharp, detailed resolution of which the camera is capable across the wide field of view that it embraces. The movie shows the details of the high-resolution image. The combination of Subaru Telescope's large 8.2 m mirror, a wide field of view, and sharp imaging represents a giant step into a new era of observational astronomy.
