In post 1 and post 2 of this series I provided information about why Sydney Observatory is building a new dome, where the dome came from and how the building program is progressing. I have already introduced you to some of the people involved in the project and our major supporters of the project, NSW Department of Aging, Disability and Home Care and the Museum of Applied Arts and Sciences.
In 1958 Harley Wood (on the right), NSW Government astronomer, traveled around NSW inspecting sites for telescopes. Here he is in Dubbo planning the next stage of the search. One of the sites he may have inspected became the Siding Spring Observatory.

This is the second in a series of blog posts about the building of a new dome on Sydney Observatory's heritage site. In my previous post I described why a new building was being constructed and who funded the project.
Mars is in conjunction with the star Antares on Sunday at 06:00am AEST. Watch Mars over the weekend as it approaches and passes close by Antares, the brightest star in the constellation Scorpius. The two are linked in name also - Antares is translated as "like Mars" or "rival of Mars" although the former seems to be preferred these days.
