by Richard McDermid Figure 1. Peculiar Galaxy Collision Is a Winner! The Australian Gemini Office has selected the winners of its most recent Gemini School Astronomy Contest. Each year since 2009, teacher-sponsored Australian students in Years 5-12 (as well as their inter-school groups and clubs) have a chance to use an hour of observing time at the 8-meter Gemini South telescope in the Chilean Andes. All they need to do is select a celestial object visible from the Southern Hemisphere and write a winning explanation as to why it would be interesting to image. The winning image of the most recent Australian Gemini Image Contest (Student Division), obtained with the Gemini South 8-meter telescope in Chile. It shows the peculiar galaxy NGC 7727 in Aquarius. It is a composite of g, r, i, and H-alpha filter images, with a total integration time of about one hour. Image credit: Ivanhoe Girls’ Grammar School Astronomy Club, Samuel Carbone (Trinity College), Travis Rector (University of Alaska Anchorage), and the AAO. A panel of astronomers, educators, and science journalists judge the mandatory teacher-sponsored entries on both the scientific interest of the target and the visual appeal of the resulting image. The bestranked proposals will have their object imaged by Gemini South and its professionally processed picture presented to the school by astronomers who will discuss the image with them. The top three entries will also be able to participate in a “Live From Gemini” program, and more. January 2016 GeminiFocus 23
