The Western Sydney Amateur Astronomy Group (WSAAG) is a group of enthusiastic and dedicated amateur astronomers based in the western suburbs of Sydney, NSW, Australia.
WSAAG provides a focus for people interested in astronomy to meet, do astronomy and have fun. Members come from all walks of life and have a diverse range of interests, some have telescopes and some don't.
We don't mind if you own a push-to or a go-to telescope or if you don't own a telescope at all. You don't need to know the sky and you don't need to be a rocket scientist to join.
All you need to join is anything ranging from an interest to a passion for astronomy.

Topic: The New Age of Dark Energy
Topic: The New Age of Dark Energy
New results from large scale supernova surveys, like the Dark Energy Survey (DES) and the Dark Energy Survey Instrument (DESI) are pushing the bounds of our measurements and understanding of dark energy. Moreover, new measurements of Hubble’s constant have led to what is called the Hubble tension. With new surveys like DEbass, and facilities like VRO, we are on the cusp of a greater understanding of the Universe, it just may be that our understanding is a lot less than we thought!
The talk will be presented via Zoom.
Visitors wishing to attend in person or online via Zoom must email us to make a booking.

The final Environmental Impact Statement was released in October 2024. The EIS and related documents can be found on the WSI Flight Paths Site.
Of particular significance is the EIS Submissions Report (See Appendix A of this report) which addresses the issues raised by WSAAG in our submission.
