On October 26 and 27, Mitaka Open House Day 2018 was held by NAOJ and other institutes with the main theme tiled “Rediscover the Solar System”. In sunny weather, this year’s event attracted a large number of visitors.
The ALMA project presented exhibitions at the ALMA building, which include the introduction of the ALMA telescope and the ALMA site in Chile, the latest scientific results, and technologies incorporated into ALMA. Also, there were annual popular attractions such as mini-lectures, ALMA-site virtual reality (VR) experience using a VR headset, satellite reception experiment with a round-bottomed pan, and radio coloring. Curious visitors were asking many questions to the ALMA staff to learn more about the ALMA site in Chile, and recent ALMA scientific achievements, etc.
