“27-foot mirrors that together assemble into the world’s largest telescope…” Right here in Tucson AZ, GMTO (Giant Magellan Telescope), has “designed to have a resolving power 10 times greater than that of the Hubble Space Telescope.”
Tucson, congratulations, and thank you GMTO, for letting us be a “partner of your success.”
