Saturday Public Sessions at the Adelaide Planetarium offer a single-day educational experience on April 18, 2026, from 11am to 4pm ACST. Experienced astronomers guide visitors through constellations, the solar system, and the universe's scale, projected on the iconic dome ceiling, featuring movies Tycho to the Moon at 11am, The Great Solar System Adventure at 1pm, and Black Holes at 3pm. Sessions provide standard seating and limited beanbag options in a comfortable setting. Children under 16 must be accompanied by a paying adult, with free lap seating for those aged 3 and under during daytime sessions, though not ideal for under 4s. Free weekend parking is available nearby, and companion card holders should contact ahead.
