There were three ticketed sessions: 7:30am to 9:30am, 10am to 12.30pm, and 1pm to 3pm. There were also a small number of limited day pass tickets which include all three sessions. Tickets were non-refundable and had to be pre-booked and pre-paid. If the sky is unclear, it will not be possible to transfer tickets to other sessions. However, we will have a video feed to share experiences of the transit from other locations, and special displays and programs to provide a rich experience even if we are unable to see the transit directly due to clouds.

Prices for single sessions: Adult $36, Child $28, Member adult $30, Member child $26.
Prices for all day passes: Adult $85, Member adult $80.

On arrival you will be given a coloured wrist band valid only for the time you have chosen, a pair of viewing glasses and a souvenir observation pass. Sydney Observatory will have a number of telescopes outside the main observatory equipped for safe solar viewing and projection.

Sydney Observatory was a hub of transit of Venus activities in 2004 – with hundreds of visitors and hearty media interest. You too can enjoy this historic event with us this year when the entire 2012 transit of Venus will be visible from Sydney from 8.16am to 2.44pm if the sky is clear.

Why is the transit of Venus important?
The transit of Venus is important scientifically and historically because it enabled the measurement of the distance of the Earth to the Sun – and so to determine the scale of the solar system.

It was Edmond Halley, of Halley’s Comet fame, who in 1716 predicted that careful observation of the start and finish of the transit of Venus across the Sun from different places on Earth would enable these calculations – although he never lived to see one himself.

Captain James Cook led an expedition starting in 1768 aboard His Majesty’s Bark ‘Endeavour’ to view the transit of Venus from Tahiti on 3 June 1769. After the transit, Cook opened a special sealed envelope containing orders from the Admiralty to search the south Pacific for a large southern continent. And so it was, on his return to England from Tahiti, that he sailed up the eastern coast of what he was soon to claim as British territory – and which would come to be known as Australia. So, Australia is deeply linked to this rare celestial event.
