Visit Sydney Observatory and catch the best view of the upcoming total lunar eclipse and Mars in opposition during a special early morning experience.
Observable in Australia on average once every 2.8 years, lunar eclipses occur when the Moon moves into the shadow of the Earth. During a lunar eclipse, light refracted onto the Moon by Earth’s atmosphere transforms the Moon into a deep red colour.
At this special event, Mars is also visible and in opposition during the total lunar eclipse.* Opposition occurs when Earth passes between Mars and the Sun. Since both planets have elliptical orbits, the distance between Mars and Earth at opposition varies. Opposition occurs every two years and two months, but this winter Mars will be the closest to Earth it has been since 2003, making Mars appear bigger and more detailed through our telescopes.
Enjoy an early morning event of astronomy with telescope viewings* and star gazing. Discover the science of lunar eclipses and oppositions and take a stroll through the Observatory before hours. Pack a picnic breakfast to bring with you and enjoy the sunrise over Sydney Harbour.
Please dress warmly as it will be a cool morning.
*This program is held regardless of the weather. If viewing of Mars and the eclipse through the telescopes is not possible due to sky conditions, other activities will be arranged. Tickets are non-refundable.
