Project Dorothy (the 50th anniversary of project OZMA, Worldwide Joint SETI Observation)



Japanese first optical SETI observations with the largest telescope in Japan (2005 - 2009)



The multisite and multifrequency Simultaneous SETI observation in Japan (Nov. 11 and 12. 2009).
We reported this project at the Astrobiology Science Conference (Apr. 2010, Houston)


SETI Workshop in Japan

Nov. 3 and 4, 2007 at Nishi-Harima Astronomical Observatory.
This is the largest SETI workshop in Japan. About 80 persons (astronomers, biologists, engineers and media) attended this workshop. There were meaningful presentations about extra-planets, astrobiology, observational implements/reports, signal analysis and education.

If SETI observers detect a candidate signal, then they would have observed the post detection SETI protocol of IAA (International Academy of Astronautics. We discussed issues of this protocol at this workshop.

Banto Yamagata




Banto Yamagata (1748 - 1821) is the first Japanese suggested the existence of ETIs.
He said "there are plants, insects, fishes, animals and humans in other planets" in his book "Yumeno-shiro"(1820).

She knows that astronomers can carry out the radio observation even in the daytime.
