From the edge of our atmosphere to the farthest reaches of space—discover it all in one night. 

Astronomy Open Night returns this September!

Get ready, space lovers—Sydney’s most spectacular night of science and stargazing returns this September. Whether you’re a lifelong astronomy enthusiast or simply curious about the universe, Astronomy Open Night offers an unforgettable evening for all ages. 

Growing every year since 1988, Astronomy Open Night at Macquarie University welcomes thousands of visitors and is now one of the largest public science events in the Southern Hemisphere. 

This year, dive into the science behind the world around you with our ever-popular Physics and Chemistry Magic Shows and hear from leading researchers as they share the latest discoveries shaping our understanding of the cosmos.

Discover exciting new highlights, including The Big Cosmic Q&A, where you can put your questions to our experts, and So You Like Science – What Now?, a special session for students planning their next steps after high school. You can also explore our new experimental short film festival, Stories Across Worlds, featuring works from the Archival Futures Collective. 

See space in entirely new ways—from immersive Planetarium sessions to guided tours of the Astronomical Observatory. Travel from the edge of our atmosphere to the farthest reaches of the universe, then step outside to explore the night sky through telescopes in our Telescope Park, guided by Macquarie astronomers and volunteers. 

Across the night, discover interactive exhibits, creative activities and new ways to engage with science—including opportunities to explore cutting-edge technology and innovation. 

With delicious food and drinks available throughout the evening, Astronomy Open Night is a celebration of discovery, curiosity and imagination—come rain or shine. 

Join us for a night that will inspire you to look up and see the universe in a whole new way.
