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.

Cracking the puzzle of unusual molecules in deep space that absorb some wavelengths of starlight is like unlocking the secrets of the Rosetta Stone, according to Rob Sharp of the Australian National University’s Research School of Astronomy and Astrophysics. “It’s the longest-standing problem in astronomical spectroscopy,” he says.

The identity of the molecules has been a mystery for 80 years, but Rob has now joined forces with chemists at the University of Sydney to try to crack the molecular code. Continue reading Is the Red Rectangle a cosmic Rosetta Stone?
