Paper Abstract

The astrobiology-related activities in the National Astronomical Observatory of Japan (NAOJ) is reported. The 45m radio telescope of the NAOJ was used to search for the interstellar glycine without success, concluding that the former claim on the detection of interstellar glycine has not been confirmed. Future observations by ALMA would clarify the existence of glycine in space. The Okayama Astrophysical Observatory of the NAOJ has been used to detect ten extrasolar planets. The Subaru telescope has also been used, under international collaborative program, to search for extrasolar planets, leading to detection of two planets. A unique trial to search for extrasolar planets by using low frequency radio data was conducted without success, however, such a method would be a basis toward radio searches by future sensitive radio astronomy instruments such as SKA and LOFAR. NAOJ has a project to search for extraplanets by a highly sensitive coronagraph. This project has also designing the Japanese Terrestrial Planet Finder for future space-based search for the Earth-type planets.
