Nov 21, 2019 Press Release: Eggs of stars sleeping in Cygnus region, the largest cradle in Milky Way; The research group has successfully found 174 high-density clumps: "the eggs" of stars or stellar clusters.
Sep 30, 2019 Press Release: UTokyo starts a full operation of Tomo-e Gozen; The Tomo-e Gozen system has been being developed for the 105-cm Kiso Schmidt telescope by mainly Kiso Observatory, Institute of Astronomy, School of Science, the University of Tokyo since 2014, and finally completed. The University of Tokyo starts a full operation of Tomo-e Gozen in October 2019.
Aug 8, 2019 Press Release: A long time ago, galaxies far, far away; Astronomers used the combined power of multiple astronomical observatories around the world and in space to discover a treasure-trove of previously unknown ancient massive galaxies. This is the first multiple discovery of its kind and such an abundance of this type of galaxy defies current models of the universe. These galaxies are also intimately connected with supermassive black holes and the distribution of dark matter.
Aug 6, 2019 Press Release: New Voyage to the Universe from DESHIMA - Japanese-Dutch Joint Development of Innovative Radio Receivers; Researchers in Japan and the Netherlands jointly developed an originative radio receiver DESHIMA (Deep Spectroscopic High-redshift Mapper) and successfully obtained the first spectra and images with it.
May 30, 2019 Press Release: Subaru Telescope captures 1800 exploding stars; By combining one of the world’s most powerful digital cameras and a telescope capable of capturing a wider shot of the night sky compared to other big telescopes, a team of researchers from Japan have been able to identify about 1800 new supernovae, including 58 Type Ia supernovae 8 billion light years away, reports a new study released online on 30 May.

Jul 3, 2018 News: MIMIZUKU achieved first light at Subaru telescope!; On July 3, 2018, MIMIZUKU, the mid-infrared instrument for the TAO 6.5-m telescope, successfully achieved the first light observation at the Subaru telescope of the NAOJ in Hawaii. We confirmed that the imaging function and its special optical device “field stacker” work well. After another engineering observation at the Subaru telescope, MIMIZUKU will be transported to TAO.
May 30, 2018 News: SWIMS sees First Light on the Subaru Telescope!; May 30, 2018, the near-infrared instrument, SWIMS, developed for the TAO 6.5 m telescope, has been installed on the Subaru Telescope of the NAOJ at Hawaii for performance verification, and successfully made its "first light" observations. SWIMS will be transported to TAO after evaluating and adjusting the observing performance based on data taken on the Subaru telescope.
Apr 6, 2018 News: OPTICAL ADAPTIVE OPTICS ACHIEVES ANGULAR RESOLUTION CLOSE TO DIFFRACTION LIMIT OF 1-M TELESCOPE; A group of researchers led by Takeo Minezaki at Institute of Astronomy (IoA), the University of Tokyo (UT), and Leonardo Vanzi at the Astro Engineering Center (AIUC), the Pontifical Catholic University of Chile (PUC), succeeded to achieve an angular resolution close to the diffraction limit by an adaptive optics system in visible wavelength mounted on the 1-m telescope of the European Southern Observatory (ESO) of La Silla in Chile.
