What the universe looks like when viewed with radio eyes

To the naked eye, the universe we can see on a clear night is dotted with thousands of stars, but what would it look like if human eyes could see radio waves?

Deep in the Western Australian outback a radio telescope is demonstrating just that by painting a picture of the cosmos in all the colours of the radio.

It’s called the Murchison Widefield Array (MWA), and over the past three years astronomers have used it to perform one of the largest sky surveys of all time, covering 90% of the southern sky.
