New Radio Telescope Could Save World Billions


A small pocket of Western Australia’s remote outback is set to become the eye on the sky and could potentially save the world billions of dollars. The Murchison Widefield Array (MWA) radio telescope, unveiled today, Friday 30 November, will give the world a dramatically improved view of the Sun and provide early warning to prevent damage to communication satellites, electric power grids and GPS navigation systems.

The $51 million low-frequency radio telescope will be able to detect and monitor massive solar storms, such as the one that cut power to six million people in Canada in 1989 during the last peak in solar activity. In 2011, experts warned that a major solar storm could result in damage to integral power supplies and communication networks of up to US$2 trillion – the equivalent of a global Hurricane Katrina.

The MWA will aim to identify the trajectory of solar storms, quadrupling the warning period currently provided by near-Earth satellites. This is timely as the Sun is due to re-enter peak activity in 2013, with a dramatic increase in the number and severity of solar storms expected, with the potential to disrupt global communications and ground commercial airlines.
