The larger the tool, the larger is the catch. Such is the motto behind the development of the world’s largest telescope. The astronomers who’re behind the making of this one are taking their trade to the next level by building it under the Antarctic ice. It’s called IceCube and will be created using thousands of spherical sensors that are being deployed into the belly of the earth. These are called Digital Optical Modules. These are inserted into holes that are melted into the ice on strings of 60 modules. These go as deep as 4,700 feet and each module takes about 11 hours to deploy.

So far, the telescope array is 95% constructed. It is expected to get done by 2011 and will have cost a whopping $271 then.
