Tuesday open evening at COSMOS Observatory

COSMOS Community Observatory on St Martin's opens its doors on Tuesday evenings for anyone curious about the night sky. Visitors can tour the observatory, learn about the COSMOS project, and hear about what makes the Isles of Scilly one of the best places in the UK for stargazing. The islands' minimal light pollution means the skies here are genuinely special, and the team are on hand to explain what you're looking at. Tickets are priced accessibly, and the evenings suit both complete beginners and those with a passing interest in astronomy.
