COSMOS — the Community Observatory St Martins on Scilly — is a work-in-progress community venture. Their observatory on the Isles of Scilly acts as a community hub and a gateway to the wonderful dark skies for tourists and locals alike. The facility is open especially throughout the tourist season and aims to enable visitors to fully appreciate the wonders of the island’s amazing unpolluted dark skies.
