What makes the MWA, the MWA.

The MWA has no moving parts. And yet, it can still point, and focus, and do all the things you'd expect of a telescope.

The MWA uses a combination of bespoke and off-the-shelf technology, and a lot of clever physics, to take incredibly detailed observations of the sky with simple antennas.

The array contains thousands of antennas, that operate in the 70-300 MHz frequency range. These are spread across several kilometres of the Murchison Radio-astronomy Observatory, on Wajarri country in outback Western Australia.

All of the astronomy data collected by the MWA is sent to a data archive in Perth, and is accessed by astronomers around the world.


The Telescope

Bringing everything together

The MWA’s location and its many different hardware and software components contribute to achieving the telescope’s science goals, through a process called radio interferometry. Read more about these elements below.
