Historicpublic observatory

GAO,a public astronomical observatory, is located on the west slope of Hakone, commanding a fineview of Mt. Fuji and Suruga bay (the Pacific Ocean), where you can learn aboutgeology and astronomy in the midst of reserved nature.  Here at GAO, we have a 50 cm diameter reflextelescope that is used on the occasion of periodic observation events.  Also, there is a planetarium that projectsseasonal stars in the night sky.  Thefirst director of GAO, when it was founded in 1957, was Dr. IsseiYamamoto.  GAO is unique since it hasover 60 years’ history as an open observatory, and was renovated and re-openedin July 2017 with brand new buildings.

Thenew building has four floors, on the top of which there are two domes; oneaccommodates a 50 cm diameter reflex telescope that is used on the occasion ofperiodic astronomical observation events. The other dome has a 20 cm Kude telescope (Goto Co., Ltd.), below whichthere is an 11 m vertical open space and on the ground floor, in the sun faceroom, you can see a 2 m diameter real time sun image (the largest in Japan)weather permitting.  You will also seethe sun spots.  The sun image looks swinging,due to the flow of atmosphere in the sky.  In the sun face room, there are eight modelsof planets, such as the Earth, the size of which is made proportional to the 2m diameter sun.

Let’slook up the stars in the sky! 

Observationevents are; once monthly regular events, and ad hoc events to observeplanets.  Also, in collaboration with aneighboring facility, we perform outdoor observational events, such as atJukkoku path.  If you are interested,please browse our homepage www.gekkou.or.jp.  In the homepage, there is a real time imageof the whole 360° skyviewed form GAO, and you can check the weather condition that will help you decidewhether to participate in the observational events or not.

CosmoWorld (3rd Floor)

 

 

Let’smake a leap to the Universe!

Atthe Cosmo World on the 3rd floor, things related to astronomy andphysics are displayed and explained.  A gigantic50 cm diameter photomultiplier tube used in the Kamiokande and the superKamiokande to detect neutrinos is displayed. We are making efforts for the visitor to appreciate that astate-of-the-art observational device was designed and constructed by Japanesescientists and engineers.  Also, thereare two Dagic Earth three dimensional (3D) projectors, which projects rotatingpictures, such as the Mars and the Universe, on the hemisphere screen.  Objects popular among our visitors arereplicas of the Galileo telescope and the Newton telescope, through which youcan actually see enlarged images.  It maybe said that the dawn of the current science was about 400 years ago, whenGalileo gazed the night sky through his hand-made telescope.  Let’s make a time slip to that ancient age!

 

SpecialExhibition of World Calendars

Sincethe astronomical events and the calendar have a close relationship, onceyearly, we specially exhibit a collection of the calendars worldwide.  Some of them use the non-solar calendar, thatwill help us to understand the diversity of culture.  To collect the calendar worldwide, we thankOISCA, a global NGO, and Embassies around the world, based in Japan.

Here,we display geology, fossils, and minerals (formerly known as the geologymuseum).  It is important to learn aboutthe Earth so as to understand the Nature correctly.  We are aiming for visitors to feel that theEarth is full of wonders and miracles. Curators are permanently available both in Cosmo and Geo Worlds.

 

 

Towardsthe new Era

Therenewed GAO also works as the venue for local senior high school students topresent their scientific research activities. On March 2017, GAO was officially recognized as a registered museum byShizuoka Prefectural Government.  Also,the Izu peninsula was officially and globally acknowledged as a World Geopark.  To cope with such new era, we atGAO are working hard to make the exhibition and explanation precise and up todate every day.  Please pay a visit toGAO that is a unique public astronomic observatory.
