The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star's life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the 'hourglass.' The unprecedented sharpness of Hubble's images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.

Macarthur Astronomical Society Inc.

patrons: Professor Bryan Gaensler & Dr. Ragbir Bhathal

We are a group of amateur astronomers of varying levels of experience, based in South Western Sydney, NSW, Australia. We hold dark sky observing sessions, invite distinguished professional astronomers to address our monthly meetings at the University of Western Sydney and hold public viewing and public lectures. We also participate in community events and provide speakers on astronomy for community organisations.

Beginners are very welcome. Observing equipment is not essential to joining, so long as you have an interest in astronomy. Assistance is given in purchasing and using a telescope. Visit our 'Join MAS' page for benefits of membership and our 'What's On' page for details of our activities.

the universe as you've never seen it before

Macarthur Astronomical Society will bring art and science together in an extraordinary six day exhibition of deep space and planetary photographs taken by members of the Society and their telescopes at the Campbelltown Arts Centre.

MAS & CCC proudly present a very special event at the Campbelltown Bicentenniel Art Gallery

Free Exhibition 4th-9th October:

The all-day exhibition will run for six days at the Campbelltown Arts Centre, Cnr. Camden & Appin roads, Campbelltown. The presentation will demonstrate the beauty and immensity of the Universe as seen from our local skies here in South Western Sydney. If you think Macarthur skies consist of just a few stars dotted against a dark background, be prepared to be astonished! 

The display will consist of deep space and planetary colour photographs taken by members of the Society, together with regular audio-visual presentations and some of the telescopes that were used to obtain the images.

A spectacular visual display will be projected onto the outside wall of the Art Centre every night during the event from dusk until approximately 10:00pm. It will be highly visible to motorists and pedestrians on Appin Road. Click > Here < to go to the Campbelltown Arts Centre Events page.

The event will end with two family orientated public talks at the same venue:
