The Minister was watching this week's episode of Science Zero on NHK World this morning, which happened to be about the proposed Thirty Meter Telescope (TMT). If built, the TMT will have a collective primary mirror that is 30 meters wide and an area of 655 square meters. By "collective," the Minister means that the primary mirror will be segmented, composed of 492 individual hexagonal mirrors that are each 1.4 meters across. If built, the TMT will gather its first light in October 2017, with scientific operations starting in June 2018.
Below are two videos that have been produced about the TMT, providing more information about the telescope and what astronomers hope to be able to achieve with it.
