Western Australia's Cosmic Leap Forward

In a groundbreaking development for radio astronomy, the Murchison Widefield Array (MWA) in Western Australia has entered Phase III, marking a significant upgrade that promises to amplify our understanding of the Universe.

A Giant Leap in Sensitivity and Data

Since its inception in 2013, the MWA has served as a powerful astronomical tool, featuring 8,192 antennas spread over a sprawling 30 square kilometers. Situated on Wajarri Yamaji land, approximately 300 km northeast of Geraldton at the CSIRO Murchison Radio-astronomy Observatory, this upgraded facility now boasts double the sensitivity and quadrupled data outputs. This leap in technology is set to unlock the secrets of the cosmos, particularly the formation of the first stars and galaxies after the Big Bang.

A Catalyst for Global Scientific Collaboration

Curtin University's Vice-Chancellor, Professor Harlene Hayne, emphasized that the enhanced capabilities of the MWA underscore the combined strength of world-class science, international teamwork, and local investment. According to Hayne, the facility is providing researchers with unrivaled insights into the universe's early epochs.

Training the Next Generation of Astronomers

MWA Director, Professor Steven Tingay, noted the transformative impact of Phase III on both the telescope and the future landscape of astronomy. "With this upgrade, the MWA is poised to not only investigate cosmic phenomena but also pave the way for the Square Kilometre Array Observatory (SKAO), the world’s largest and most sensitive radio observatory currently on the rise at the same location," he said.

An Investment in the Future

This $5.4 million investment was bolstered by contributions from MWA's international partners in Australia, Canada, China, Japan, Switzerland, and the USA. Key electronic components were supplied by the Shanghai Astronomical Observatory in collaboration with the Curtin Institute of Radio Astronomy, showcasing the global relevance of the MWA. Support from both State and Federal Governments of Australia, along with partnerships from local industries ranging from computing to technology development, also played a vital role.

Celebrating a Milestone

To commemorate this significant upgrade, a three-day annual conference hosted by ICRAR-Curtin took place from August 27-29, 2025, gathering representatives from MWA’s global partner organizations.

Strengthening Community Engagement

As operations continue, the MWA is dedicated to fostering cultural and community engagement, forging long-lasting partnerships with the Wajarri Yamatji communities and ensuring a rich legacy for future generations.

This ambitious upgrade not only solidifies the MWA's place as a leader in astronomical research but also embodies its commitment to education and local economic growth.
