Welcome to the website of the Nelson Science Society (NSS) and its Astronomy Section (AS). NSS is a branch of the Royal Society Te Apārangi and promotes science within the Nelson/Tasman region by holding regular scientific talks from a variety of experts throughout the year and by promoting science education in schools and colleges.

The Astronomy section is run as an independent constituent of the NSS and maintains its own program of events (see Astronomy Section pages for full details and newsletter).

See the Support page for details of how you can become a member.
