The Telescope

The Murchison Widefi eld Array (MWA) is a low-frequency radio telescope operating between 80 and 300 MHz. It is located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia, the planned site of the future Square Kilometre Array (SKA) lowband telescope, and is one of three telescopes designated as a Precursor for the SKA. The MWA has been developed by an international collaboration, including partners from Australia, India, New Zealand, and the United States. Read more about the telescope...

The Science

The MWA is performing large surveys of the entire Southern Hemisphere sky and acquiring deep observations on targeted regions. It enables astronomers to pursue four key science objectives. The primary endeavor is the hunt for intergalactic hydrogen gas that surrounded early galaxies during the cosmological epoch of reionization. The MWA will also provide new insights into our Milky Way galaxy and its magnetic field, pulsing and exploding stellar objects, and the science of space weather that connects our Sun to the environment here on Earth.
