Online Exhibition - Aaron Greenville

Aaron Greenville has been fascinated with wildlife and the environment all his life. He now is a desert ecologist, which takes him to some of the most remote regions of Australia. Aaron is interested in wildlife and landscape photography. More recently, he has taken up astro-photography and spends many nights capturing images to build a final photograph of nebulae or planets. Some of his work has featured in magazines, brochures and books. Aaron hopes to inspire people to conserve our world by capturing the wonder of the natural universe in his photography.

The ESA Ecology in Action Photographic Competition is an annual event attracting amazing images celebrating the diversity of landscapes and ecosystems within Australia and New Zealand. In 2014, a new award was added for Best Portfolio and attracted a cash prize as well as the opportunity for an online photographic exhibition of the winner’s work. The inaugural prize was shared by Dr Aaron Greenville from the University of Sydney and Richard Wylie, based at Monash University, Victoria. Aaron now presents the first of these online exhibitions featuring the images which won him best portfolio in the 2014 competition, as well as some additional images showcasing the full scope of his photographic interests and talent.

Centaurus A

Centaurus A

Centaurus A (NGC 5128) is a giant elliptical galaxy around 10?~@~S16 million light-years away. It was discovered in 1826 by Scottish astronomer, James Dunlop, from his home in Parramatta, Australia. I was happy to capture part of the relativistic jets (look just to the top-right of galaxy). These are extremely powerful jets of plasma from a supermassive black hole at the centre of the galaxy, which has a mass equivalent to 55 million solar masses!

Fresh eyes

Fresh eyes

There were rumours that the local leopard had cubs. We headed out for a game drive only to stop when our guide heard the alarm calls from a flock of guineafowl. From the bush, the leopard came and sat down in the open. Then her cub followed, exploring its new world. South Luangwa, Zambia.

Equipment: Canon 1D mk 3DSLR, Canon 100400mm lens.

Comet LoveJoy C/2014 Q2

Comet LoveJoy C/2014 Q2

Discovered by Terry Lovejoy from Australia in 2014, this comet brightened to roughly magnitude 4 and became one of the brightest comets located high in a dark sky since comet C/1995 O1 (Hale-Bopp) in 1997. It was visible to the naked eye for experienced observers. Can you see the small galaxy and globular cluster? The small galaxy has a magnitude of +12. At our very best and under dark skies, we can see +5 or 6!

Equipment: Canon 100400mm lens at 400mm, Canon 1D mk 3DSLR piggybacked on top of the telescope. No guiding
