New telescope as big as Earth itself I love Astronomy as a hobby. This is really cool. Using multiple radio telescopes and a super computer, the system will have the power of a radio telescope with the diamater of the Earth, which is about 7,500 miles. They call it the High Frequency VLBI Array and it is 3,000 time more powerful than the Hubble telescope in orbit. On the downside, it is a radio telescope, not optical so it won't be able to "see" images in visible light that humans see. But, that is ok because most of the Universe can't be seen through optical techniques because of dust clouds and such. It would be cool if SETI used this new telescope to find aliens. The international project uses radio dishes in Arizona, Spain, Finland and Chile. Signals from each are time-stamped with atomic clocks and pieced together with a supercomputer. The result is an instrument with an unprecedented ability to distinguish between two closely situated objects far away in the sky.
