AAO leads key instrument design as BlueMUSE enters design phase

Australian Astronomical Optics (AAO) at Macquarie University is playing a leading role in the development of BlueMUSE, a next-generation spectroscopic instrument for the European Southern Observatory (ESO)’s Very Large Telescope (VLT), following the project’s approval to enter its Preliminary Design Phase in February 2026.

AAO is a core partner in the international collaboration and is responsible for leading the design of the instrument’s opto-mechanical structure, including key components that enable BlueMUSE’s wide field of view and high performance.

Based on the successful technology of the MUSE instrument installed at the VLT, BlueMUSE is designed to capture shorter wavelengths of blue light, enabling astronomers to separate colours and components with unprecedented precision. In doing so, BlueMUSE will reveal subtle details about the universe, offering fresh insights into its biggest mysteries.

Jonathan Moller, a mechanical engineer at AAO, is playing an important role in developing the instrument.

“To take part in creating technology that answers fundamental questions about the universe – and our place within it – is incredibly rewarding,” Moller says, adding, “I hope this gives humanity perspective about what really matters.”

As with many cutting-edge astronomical projects, BlueMUSE’s development reflects years of work, technical challenges, and international collaboration. The project itself is expected to take around eight years to complete.

“The devices we build push the boundaries of engineering and technology, requiring unique technical skills, creativity, and perseverance to find solutions that meet scientific objectives,” Moller explains.

Dr Zhemin Cai, who is also part of the engineering team at AAO, was immediately captivated by the BlueMUSE project.

As a multi-physics mechanical engineer, the experience is giving him a strong sense of purpose.

“Knowing our engineering work directly supports scientific discovery makes it deeply meaningful,” he says.

The project has recently been approved to enter its design phase and already shows bright signs of helping illuminate the mysteries of the Atacama sky in the near future. One complete, Moller expects to feel a deep sense of pride.

“Knowing I had a small part in this incredible undertaking will give me immense professional satisfaction and allow me to share a special connection with everyone involved,” he says.
