Develop new methods to look deeper into space

Australian researchers have recently developed a method that allows scientists to look deeper into space.

In the past, the only way to look deeper was through the use of telescopes with an atomic clock to accurately record the time when signals were detected from an object in space. .

However, experts from Australian research institutes such as the Scientific and Industrial Research Organization (CSIRO), the National Metrology Institute, the Australian Study and Research Network, the University of Adelaide and Macquarie University, led by the Australian National University (ANU), for the first time demonstrated that two radio telescopes can connect through a stable frequency reference.

Two radio telescopes can be connected via a stable frequency reference.

Frequency reference is the use of a frequency standard to establish a high-precision frequency that can be used to create reference points.

According to Ken Baldwin, co-author of the ANU study, this new technology is particularly useful for a global effort to detect radio waves from deep in space with a sensitivity of about 50 times.

The highly stable frequency reference reference method promises to replace the use of expensive atomic clocks at a cost of up to $ 200,000 / unit.

SKA is a radio telescope project under construction in Australia, New Zealand and South Africa. Once completed, the single telescope will be connected to create the world's largest frequency telescope.

Mr. Baldwin stressed that this new technology does not require any significant changes to fiber optic networks and is easy to implement.

Through testing on fiber optic cable, researchers have shown that stable frequency standard generation does not affect data or calls on other channels.

This plays an important role in gaining cooperation from telecommunications companies that own these fiber optic networks.
