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.
Brenan Dew is an astronomy guide at Sydney Observatory and is currently working on his PhD at Macquarie University. Below he discusses ancient astronomy and the Egyptians. In our modern society it is well known that the Earth is constantly spinning on its axis, completing one revolution in approximately 24 hours.
Tiffany Day is one of our astronomy guides and in this post she discusses robotic explorers of our Solar System and beyond. If you've been paying attention to recent space news, you would have heard that the New Horizons space probe completed a successful flyby of Pluto - our first ever high resolution view of the planet in the history of our species - back in July of this year, or that the Curiosity rover successfully landed on Mars three years ago, and has just recently provided the first hard evidence of liquid water on Mars.
Regular solar observer & correspondent Harry Roberts previously reported on the complex Delta Group of sunspots, AR12422. Here he follows up with a report on the group's coronal loops. AR12422: Coronal Loops.?????????????????????????????????????????????????????????? Harry Roberts.

November has a spectacular treat in store for all of you early-birds! During late October, Venus has been dancing in the pre-dawn sky with Jupiter and Mars. This dance continues in early November, with Venus and Mars at their closest on November 3 and 4, after which Venus slowly starts to retreat towards the east horizon.
Regular solar observer & correspondent Harry Roberts reports on active region AR12422, a complex Delta Group: AR12422: Complex Delta Group.????? ??????????????????????????????????????????????? Harry Roberts Hale’s invention of the visual magnetograph and the Hale Classification of sunspots is a heroic tale, but we can only touch on it here.
What is the closest?star, in the night-time sky,?to Earth? Almost everyone answers Alpha Centauri, the brighter of the pair of Pointer stars. But Alpha Centauri is in fact a?system of three stars.
This Friday, October 9, at dawn the Moon will move in front of Venus and hide, or occult, it. These occultations of Venus are visible from Earth once or twice per year, yet from any one location, such as Sydney, it can be about 5 to 10 years between occurrences.
Orionids meteor shower expected to peak on 21 October To help you learn about the southern night sky, Sydney Observatory provides a written guide and a sky map or chart each month. This month's guide is presented by Dr Andrew Jacob (pictured, right), Curator of Astronomy at Sydney Observatory.
As Comet 67P/Churyumov-Gerasimenko reaches its closest point to the Sun, perihelion, on August 13, its activity is increasing. This short lived jet was spotted by the narrow angle camera on board ESA's Rosetta spacecraft.
