Daniel Tran, a year ten student at PAL College in Cabramatta, a suburb in southwestern Sydney, has photographed the Glowing Eye Nebula, a ghostly cloud of gas that has lasted at least 3,000 years and surrounds a dying star some 7,000 light years from Earth.

Daniel took the photograph using one of the world’s biggest telescopes—the giant 8.1­metre Gemini South telescope in Chile, in which Australia has a 6.2 per cent share. His precious hour’s worth of observing time on the telescope was the 2009 prize for winning the Australian Gemini School Astronomy Contest, which aims to inspire the next generation of Australian astronomers by involving students in the process of real astronomy at a major professional facility.

Bringing dark corners of the Universe to light

Using the Gemini South telescope in Chile, a team of astronomers led by Joss Bland-Hawthorn of the University of Sydney revealed the faint, outer regions of the galaxy called NGC 300, showing that the galaxy is at least twice the size as thought previously. The findings suggest that our own Milky Way galaxy could also be bigger than the textbooks say.

But Joss’s telescope observations are just a part of his contribution to astronomy. He is also helping to pioneer a new technology known as astrophotonics, which uses optical systems to improve our understanding of the Universe. Continue reading Bringing dark corners of the Universe to light

Mount Stromlo Observatory rising from the ashes

The Mount Stromlo Observatory of the Australian National University (ANU) is rising from the ashes of Canberra’s 2003 bushfires, after an investment of millions of dollars into cutting-edge technologies and facilities.

The Mount Stromlo site—home to the ANU’s Research School of Astronomy and Astrophysics (RSAA)—no longer acts as a research observatory, but rather as a high-tech hub developing astronomical instruments for the world’s most advanced telescopes. Staff at the RSAA’s Advanced Instrumentation and Technology Centre have already built multi­million dollar instruments, such as the Near-Infrared Integral-Field Spectrograph (NIFS) for the Gemini North Telescope which provides images in the infrared equivalent to the Hubble Space Telescope in the optical range.

From mapping a continent to surveying the Universe

Australia’s first observatory was built on the shores of Sydney Harbour by Lieutenant William Dawes of the First Fleet, on the point where the southern pylon of the Sydney Harbour Bridge now stands. Optical astronomy was essential for maritime navigation, and for providing precise location measurements for surveying the new continent.

The country’s first major observatory was established in 1821 at Parramatta by Thomas Brisbane, Governor of New South Wales and, later, President of the Royal Society. The observatory was used to discover and record the galaxy NGC 5128—a now much-studied galaxy that radio astronomers know as Centaurus A, within which sits a super-massive black hole (see Recording the impact of a super-massive black hole).
