Petition for National Legislation for Light Pollution Regulation and Dark Sky Preservation.

Hi SASI friends,
We try not to impose on our valued followers, but there is a very important petition to try and limit light pollution so we can continue to see the wonders of the sky at night, even from our suburban location in Oyster Bay. In the last 10 years I have noticed the sky is getting so bright that there are objects like faint galaxies that we can no longer see at all, and we have lost our view of the Milky Way entirely. If we don't do something about it, our children won't be able to see stars, and if we can't see something we unfortunately won't care about it. It would be a shame for future generations to not ask the big questions about the universe because they can't see the stars to be inspired to think about it.

The petition's closing date is 19 September, and we have 9,060 signatures of the required 10,000 for the petition to be heard in parliament. So, we need an additional 940 signatures in the next 4 days.

Please sign the petition via the link below and pass it on to all your contacts for their help.

2025 August Open Night Recap.
It was another clear night last night, and it seemed everyone enjoyed the experience. Thank you to all who attended as this event makes a major contribution to our astronomical society being able to fund the expense of maintaining an observatory for the education and entertainment of the community. I hope we contributed to some budding young astronomers heading down the path of a career in Science, Technology, Engineering and Mathematics. 🔭👩‍🎓👩‍🏫
