The Sydney Science Festival is all about bringing science to life, and this year's program is the biggest yet with more than 200 events planned.
The festival runs for almost two weeks in August, across National Science Week, with chances for budding scientists of all ages to learn from some of Australia's best science minds.
On Friday August 10, at the Powerhouse Museum from 6pm to 8pm, festival ambassador and astronomer Lisa Harvey-Smith will present the When Galaxies Collide keynote talk on how collisions between our galaxy and its neighbours will change the stars in our night sky ... though the next one isn't expected for 3.8 billion years.
Other experts on the line-up include Indigenous astronomer Kirsten Banks, leading A.I. expert Ellen Broad, the inimitable Dr Karl Kruszelnicki and the 2018 Australian of the Year, quantum physicist Michelle Simmons.
In Centennial Park you'll find Science in the Swamp, a free family-friendly day with roving dinosaurs and scientists to point out "super powers" you can find in nature.
Kids will also love Super Science Saturday at the Australian Museum and Big Science Day at the Powerhouse, both with interactive science shows.
The Sydney Science Festival is produced by Museum of Applied Arts and Sciences and Australian Museum and collaborated with more than 80 science organisations.
