Special interest groups

If you have a passion for astronomy, consider joining the Flamsteed Astronomy Society, a Royal Museums Greenwich-affiliated special-interest group.

The Flamsteed Astronomy Society (for age 18+)

The Flamsteed Astronomy Society explores new concepts and discoveries in astronomy. Members and world-class astronomers meet in the National Maritime Museum's Lecture Theatre every month during the winter, and in summer there’s an active programme of visits and activities. The group also has ‘observing sessions’ out and about, and special sessions using the Royal Observatory’s 28-inch telescope.

Membership of the Flamsteed Astronomy Society costs from £74 for Single Membership, £115 for Joint Membership and £63 for Concessionary Membership. This includes the price of the standard Royal Museums Greenwich Membership.
