The Thirty Meter Telescope (TMT) International Observatory (TIO) is an extraordinary international scientific endeavor that has the potential to revolutionize our understanding of the universe and our place within it. TIO’s preferred site is Maunakea, and TIO is working to be a model observatory that demonstrates deep respect for the significance of Maunakea to the community.
TIO’s members are the California Institute of Technology, University of California, the National Institutes of Natural Sciences of Japan, the Department of Science and Technology of India, and the National Research Council of Canada. The Association of Universities for Research in Astronomy is a TIO Associate. Major funding has been provided by the Gordon and Betty Moore Foundation.
The National Science Foundation has provided funding for recent design and development work. Any opinions, findings and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.
