Thebigger a scope ’s mirror , the better resolution it has . dig has just begun on a new telescope that will be truly enormous , called the Giant Magellan Telescope .
The GMT will be be big—24.5 meters ( 83.5 foundation ) in diameter , high up in the Chilean desert . It ’s one of several mammoth telescopes under construction . It could help researcher count at upstage galaxies , exoplanets … and who love what else .
The scope “ opens a whole fresh potency for discovering things we did n’t look to , and ways to handle questions we ’ve wanted to go after for eld but did n’t have the applied science to resolve , ” Pat McCarthy , the telescope ’s Vice President for Operations , told Gizmodo .

The scope lie in of seven 8.4 m ( 28 foot ) mirror arranged in a honeycomb shape , atop a concrete weapons platform , inside a 63 meter- ( 206 feet- ) tall inclosure . It ’s located 2,514 meters ( 8,248 feet ) up in the Atacama desert , known for its placid , dark and vindicated sky . structure will postulate digging out seven meters ( 23 feet ) of satisfying rock ‘n’ roll in society to place the concrete . The telescope ’s first light is expected for 2024 .
The GMT will mention optical and infrared wavelengths of light , and will be equipped with specialadaptive opticsto dispatch the blurring due to the atmosphere . This will allow it to view item in the far aloofness , like galaxies from the first billion years of the universe ’s existence . It should also help scientist directly image exoplanets fence in other star , and fix the variety of atom in their atmospheres .
Though the GMT will have resolution sound than the Hubble Space Telescope , there ’s a trade-off between being on the dry land and being out of doors of the Earth ’s atmosphere . “ From the ground , you should be able to observe nigher to the genius but will probably be limit to moderate major planet - to - whizz brightness ratios , ” Aki Roberge , scientist at the NASA Goddard Space Flight Center ’s Exoplanets and Stellar Astrophysics Laboratory told Gizmodo in an email . “ From quad , you ca n’t get as close to the ace ( because of the smaller scope diameters ) , but should be able to notice much fainter planets . ”
What that boils down to is that these gigantic telescopes will be good for observing exoplanets around yard - nanus stars , she say . place telescopes equip with starlight - blocking coronagraphs could well observe planets around sun - like stars . Both are important candidate forextra - terrestrial life .
scientist from around the macrocosm will compose proposition , reviewed by a selection commission , in rules of order to set aside telescope time . The scope ’s founders let in aconsortium of universitiesand funding will come from countries around the world , including South Korea , Australia , and Brazil , as well as the National Science Foundation and others agency .
The scope is just one of a host of “ super turgid telescopes ” on the horizon , let in thecontroversialThirty Meter Telescope design for Hawaii and the highly Large Telescope ( yes , that ’s its name ) the European Southern Observatory is plan for Chile . You might be aware of larger radiocommunication telescopes — when Ivisited Arecibo , I learned that radio telescopes must be much larger to collect the longer - wavelength luminance , do n’t worry quite as much about the cleanliness for their looker .
Bigger is honest when it come to looking at space , and telescopes are entering an era where they ’ve become really tremendous . Who knows what else there is to break in our universe .
