Save our stars
For decades astronomers have been aware of the impact of light pollution on the night time environment. As the love of light and our cities grew, astronomical observatories moved to more remote places. For this reason the national observatory moved from Sydney Observatory, then to Canberra and then to Siding Spring Mountain. The home of Australia's first Dark Sky Park.
For tens of thousands of years, our ancestors experienced a sky brimming with stars every night. This was ordinary, but has become extraordinary with the advent of light pollution.
