To help you learn about the southern night sky, Sydney Observatory provides a guide and a sky map or chart each month. This month's guide is presented by Melissa Hulbert, Sydney Observatory’s Astronomy Programs Coordinator.
Einstein's Relativity is a little over a century old, and is still our best description of space and time. But trying to explain this unintuitive theory of distorted space and time, without using mathematics, has always been a challenge.
From late January through February 2016 all five naked eye planets will be visible at once in the pre-dawn sky. This planetary arrangement occurs on average every 12 years. What can I see and when? To see these five planets - Mercury, Venus, Mars, Saturn and Jupiter - look to the east between about 5:15am and 5:30am any time from Saturday January 23 to the end of February.
Is there a planet orbiting Proxima Centauri, our closest night time star? In 1915 Robert Innes discovered that Proxima Centauri was our closest star not far from bright Alpha Centauri. Last year I wrote about the centenary of this discovery, its Australian connection and how to see Proxima Centauri for yourself.
Silvia Choi is an astronomy guide at Sydney Observatory and avid meteor chaser! Below she discuss upcoming meteor showers for 2016. You may have heard about the Geminids meteor shower that appeared in the night sky in December 2015.
Aina Musaeva is an astronomy guide at Sydney Observatory and PhD student at Sydney University. On a recent overseas trip she made an interesting discovery and link with a very special object at Sydney Observatory.
Liam Birchall is an astronomy guide at Sydney Observatory. Below he continues his series on the lunar landing hoax. Why does the flag wave on the Moon if there is no wind? Here is a follow up post related to continual rumblings and outbursts by those who see the entire Moon landings in the 60’s and 70’s as a gigantic hoax.

To help you learn about the southern night sky, Sydney Observatory provides a guide to the night sky and a sky map or chart each month. This month's guide is presented by Dr Nick Lomb, Sydney Observatory's past Curator of Astronomy and Dr Andrew Jacob, Sydney Observatory's Curator of Astronomy.
The Big Bang, dark matter and the universe, all in a night’s work for our astronomy guide and PhD student Carlos Bacigalupo. Last month Mia came to Sydney Observatory to discuss her class project on the Big Bang with Carlos.
To help you learn about the southern night sky, Sydney Observatory provides an audio guide/podcast, transcript of that audio, and a sky map or chart each month. This month's guide is presented by Geoffrey Wyatt, Astronomy Educator at Sydney Observatory (pictured at right).
This annual publication, written by former MAAS curator Dr Nick Lomb, has been providing stargazers with everything they need to know about the southern night sky for the past 26 years. The 2016 guide contains monthly astronomy maps, viewing tips and highlights, and details of the year’s exciting celestial events.
Liam Birchall is an astronomy guide at Sydney Observatory. Below he discusses the lunar landing hoax. As the clouds clear and our companion moon is waxing itself into the eastern sky, we here at Sydney Observatory have been hearing once again rumblings about the Moon Landing “Hoax” on commercial radio and thought to revisit some of these spurious claims. According to the hoax view, NASA did not land on the moon in July 1969 as many believe.
Regular solar observer & correspondent Harry Roberts reports on a Delta group of sunspots, AR12443, that didn't flare strongly. AR12443: Delta group ‘that didn’t’ Of the four Hale magnetic classes of sunspots, Delta is known to be the most active for solar flaring.
