UA Mirror Lab Casts Third Mirror for World's Largest Telescope

Scientists at the UA's Steward Observatory Mirror Lab are casting the third mirror in a series of seven that will be used to construct the Giant Magellan Telescope. Once completed, the telescope will be the largest in the world and have a resolution 10 times greater than the Hubble Space Telescope. The mirror will spend the next few months spinning inside a large furnace, which will heat the glass enough to melt it and then slowly cool it down.
