May NSA Club Meeting

On Friday, May 12, Dean Ketelson of the Richard F. Caris Mirror Lab of the University of Arizona in Tucson will speak on the Lab's primary project, the Giant Magellan Telescope. The telescope, scheduled for commissioning in 2022, will consist of 7 mirrors, each 8.4 meters in diameter.  It will be located in Chile, at one of the highest and driest locations in the world.  The Giant Magellan Telescope will seek answers to questions such as how the present universe took shape after the Big Bang and what is its ultimate fate, how were the first galaxies formed, what is the nature of dark energy and dark matter, and is there life on other worlds.
