Artists concept of the completed Giant Magellan Telescope. The Giant Magellan Telescope is completing its last main mirror, with the objective to exceed current space telescopes in level of sensitivity and resolution. Last week, the University of Arizona Richard F. Caris Mirror Lab closed the cover on almost 20 loads of the purest optical glass inside an one-of-a-kind oven housed underneath the stands of the Arizona Wildcats Football Stadium. The most just recently completed primary mirror is all set for integration into a huge assistance system prototype early next year for final optical efficiency testing. When put together, all 7 mirrors will work in concert as one monolithic 25.4-meter mirror– a diameter equivalent to the length of a mature blue whale– resulting in up to 200 times the sensitivity and four times the image resolution of todays most advanced space telescopes.

7 of the worlds largest mirrors will browse the Universe for life beyond Earth
The Giant Magellan Telescope starts the four-year procedure to fabricate and polish its seventh and final main mirror, the last required to complete the telescopes 368 square meter (3,961 square foot) light gathering surface, the worlds largest and most challenging optics ever produced. Together, the mirrors will collect more light than any other telescope around, allowing humankind to open the secrets of deep space by providing comprehensive chemical analyses of celestial objects and their origin.

Distinct Glass Melting Technique Underway
Last week, the University of Arizona Richard F. Caris Mirror Lab closed the lid on almost 20 lots of the purest optical glass inside a distinctive oven housed below the stands of the Arizona Wildcats Football Stadium. The spinning oven will heat the glass to 1,165 ° C( 2,129 ° F) so as it melts, it is required external to form the mirrors curved paraboloid surface. Determining 8.4 meters (26.7 feet) in diameter– about two stories tall when basing on edge– the mirror will cool over the next 3 months before moving into the polishing stage.

At 50 million times more powerful than the human eye, “the telescope will make history through its future discoveries,” shares Buell Jannuzi, Principal Investigator for the fabrication of the Giant Magellan Telescope primary mirror sections, Director of Steward Observatory, and Head of the Department of Astronomy at the University of Arizona. “We are delighted to be closing in on another milestone in the fabrication of the Giant Magellan Telescope.”

Combination and Testing
The most just recently finished main mirror is ready for combination into a giant support group model early next year for last optical efficiency testing. This screening will act as the gown practice session for all 7 main mirrors. When put together, all seven mirrors will work in show as one monolithic 25.4-meter mirror– a size equivalent to the length of a mature blue whale– resulting in up to 200 times the sensitivity and four times the image resolution of todays most innovative area telescopes.
The Giant Magellan Telescope will be the very first very large telescope to finish its main mirror selection. With strong operational infrastructure completed at the telescope site in Chile, focused production is taking place on the telescopes critical subsystems before beginning on the enclosure.

” We are in a crucial stage of fabrication, with much of the manufacturing occurring in the United States,” shares Robert Shelton, President of the Giant Magellan Telescope.
The 39-meter-tall telescope structure is being manufactured with 2,100 lots of American steel at a freshly built manufacturing center in Rockford, Illinois, and fabrication of the telescopes very first of seven adaptive secondary mirrors– a one-for-one set with each of the seven main mirrors– is underway.

Appealing Capabilities and Expectations
” The combination of light-gathering power, effectiveness, and image resolution will enable us to make brand-new discoveries across all fields of astronomy,” shares Rebecca Bernstein, Chief Scientist for the Giant Magellan Telescope. “We will have an unique combination of abilities for studying worlds at high spatial and spectral resolution, both of which are crucial to figuring out if a world has a rocky composition like our Earth, if it contains liquid water, and if its environment includes the right mix of particles to suggest the existence of life.”
The telescope is expected to see first light by the end of the years, and will work to address a few of mankinds most pushing concerns: Where did we come from? Are we alone in the Universe?
