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 audio sky guide is presented by Mel Hulbert, astronomy educator at Sydney Observatory.
by Stefan Tibar and Herve Meteyer On Sunday, 18th of July 2011, two young fellows from France have come to Sydney to renew the long French-English rivalry about the transit of Venus… Who, between French and British scientists could determine more accurately the distance between the earth and the sun using the observations made during the transit of Venus?

A view of the 154-km wide Gale Crater on Mars, the selected landing site for the Curiosity rover. It is a mosaic of images from NASA's Mars Odyssey orbiter. Note the five kilometre high mountain inside the crater - its resemblance to a map of Australia is uncanny and maybe it was that likeness that led the International Astronomical Union in 1991 to name this crater after an Australian astronomer.

July 2011 marks a first in this country with the Australian Astro Imaging Conference held this month on the Gold Coast, Queensland. This is the first time a large scale conference on imaging has been held in this country, and with a full house, indicates the interest and need for a conference of this scale to be held on a regular basis.
Each Year The Central West Astronomical Society (CWAS) hosts an event for amateur astronomers and the general public in conjunction with the David Malin Awards, arguably Australia’s premier astrophotography competition.

The giant planet Neptune was imaged by the Voyager 2 spacecraft on 16 & 17 August 1989. Courtesy NASA/JPL Johann Gottfried Galle wrote to the French mathematician Urbain Jean Joseph Leverrier on 25 September 1846: The planet whose position you pointed out actually exists.
One of the most important aspects of the annual meeting of the Astronomical Society of Australia is its strong support for students. Today's honours level and postgraduate students are tomorrow's professional astronomers, of course.
Today in Adelaide it is July 6, 2011, otherwise known as the fourth day of the Astronomical Society of Australia's annual conference . I learnt a lot about 'particle astronomy' today. Normally we see the universe when photons reach our telescopes.
I have to admit that my overall feeling here in Adelaide on the third day (July 6, 2011) of the Astronomical Society of Australia's annual conference is confusion. The range of topics is vast, the science presented reaches every niche and the telescopes mentioned are located across the globe and even in space.

The second day (July 5, 2011) of the Astronomical Society of Australia's annual conference continued the theme of New Surveys. This time it was the turn of the radio astronomers to tell us about their upcoming surveys.
