Astronomy Family Night at The Calyx

Join us for a night of astronomy and star gazing surrounded by the gorgeous inBLOOM plant display at The Calyx, in the heart of the Royal Botanic Garden Sydney.

Discover what the night sky teaches you with First Nations astronomer Drew Roberts from Shared Knowledge, then travel through space to visit these mysterious planets far from Earth! More than 4000 planets have been discovered around other stars — tonight Professor Fred Watson will take you on a journey to these strange 'other' worlds. How do astronomers discover them? Find out how astronomers detect exoplanets around other stars, and hear about the most interesting planets we have found out there!

Powerful telescopes from the Northern Sydney Astronomical Society will allow an amazing insight into the world beyond Earth.
