Improved detection of radio waves from space

6 mayo 2015

Researchers have developed a very sensitive high frequency amplifier for radio telescopes used on Earth. The amplifier generates extremely little internal electromagnetic noise and will help measure our planet from space more precisely than ever before. The position of radio telescopes will be pinpointed with a precision to approximately one millimeter — a tenfold improvement in accuracy. The measurement technique relies on radio telescopes picking up radio waves emitted by objects in space; the more accurately scientists can determine the positions of the radio telescopes, the more precisely they can measure various characteristics of the Earth.
