A telescope located deep in the West Australian outback has shows what the universe would look like if human eyes could see radio waves.

Our galaxy, the Milky Way, is a band across the sky and the dots beyond are some of the 300,000 galaxies observed by the telescope for the GLEAM survey by the Murchison Widefield Array – a tile of which is seen in the image above.

As for the radio waves, red indicates the lowest frequencies, green the middle frequencies and blue the highest frequencies.
