Director’s Welcome

Welcome to the MMT Observatory web site.  Together with the Magellan telescopes, the 6.5-meter MMT hails as the 14th largest telescope in the world. The MMT staff and I are proud of the scientific impact of the Observatory and of its very rich heritage. We hope that all visitors to our web site, from professional astronomers to interested members of the public, find the information provided here to be both interesting and useful.  We invite you to learn about our history, current facilities, staff, and instrumentation.  For an even better experience come visit us
