LOFAR-New telescope technology for deep space survey

[search]

"LOFAR started as a new and innovative effort to force a breakthrough in sensitivity for astronomical observations at radio-frequencies below 250 MHz. The basic technology of radio telescopes had not changed since the 1960's: large mechanical dish antennas collect signals before a receiver detects and analyses them. Half the cost of these telescopes lies in the steel and moving structure. A telescope 100x larger than existing instruments would therefore be unaffordable. New technology was required to make the next step in sensitivity needed to unravel the secrets of the early universe and the physical processes in the centers of active galactic nuclei."<br /><br />http://www.lofar.org/p/ast_sc_epoch.htm

Sorry folks.<br />The link is now together with a brief explanation.<br />Explore the astronomy sector of the link. Interesting for those who like Big Bang and primordial times of Universe.
