An annual summer event, NAOJ Nobeyama Open Campus was held on August 27 this year. Despite the rainy weather, the exhibition area was filled with energy of more than 1600 visitors.

ALMA Project has participated in this event every year, as the Nobeyama Radio Observatory (NRO), established in 1982, was the birth place of ALMA which was planned as a next- generation telescope succeeding to NRO. This year’s exhibition of ALMA includes posters showing the latest achievements and the mechanism of the ALMA Telescope; diorama model of the ALMA Array Operations Site at an altitude of 5000 meters with a reduction scale of 1/10000; and a Band 10 receiver cartridge developed by NAOJ. This year’s mini-lecture was given with a theme of the birth of planets and galaxies. Another new attraction, which was presented for the first time in Nobeyama Open Campus, was a virtual tour to the ALMA site in Chile using a virtual reality (VR) headset. This experience has been verified to be very real according to the ALMA staff members who have already been there. It was a good way for many people to experience the scenery and night sky of the ALMA high site at 5000 meters which is not open to the public.
