Green light for ISON: Comet blazes in stunning shots
It's not at all clear whether Comet ISON will become "the comet of the century," as skywatchers hoped a year ago, but it's certainly become a beautiful sight for photographers with the right kind of telescope. Adam Block captured a stunner on Tuesday morning, just before sunrise, using the 0.8-meter Schulman Telescope at the University of Arizona's SkyCenter atop Mount Lemmon.

UA Machining and Welding Center Wins NASA Award
Welders and machinists at the University of Arizona's Machining and Welding Center have been recognized by NASA with an award for "extraordinary dedication and contributions" to the James Webb Space Telescope project.
Squinting At Saturn Through 17th Century Technology
(ISNS) -- A team of French researchers has shed light on an important moment of astronomical history by testing the old lenses used by astronomer Jean-Dominique Cassini when he observed a minuscule gap between two of Saturn's rings in 1675. Questions have lingered over whether it was possible to see this gap, which was later named the "Cassini Division," with the optics he had at his disposal.
UA Mirror Lab Casts Third Mirror for World's Largest Telescope
Scientists at the UA's Richard F. Caris 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.

278 E. Congress
Distinguished Professor of Astronomy Chris Impey takes us on a tour of mirror-making and the quest to capture light from remote regions of time and space. The largest mirrors in the world are created under the football stadium at the University of Arizona, and we use them to see billions of times fainter than the human eye. Big telescopes are time machines, taking us close to the big bang, and a time when the universe was hot and dense and no stars of galaxies had yet formed. Join us for a multimedia tour of frontier technology and the limits of cosmic vision.
