The Observatory

Origins and History

In 2019, the international initiative "On the Moon Again" brought together Mializo Razanakoto — astronomy enthusiast and founder of the Haikintana association — and Sylvain Bouley, a French planetary scientist. Inspired by making astronomy more accessible in Madagascar, they conceived an ambitious project: a robotic observatory dedicated to education and inspiration.

The idea took shape through a meeting with Charles Gassot, CEO and founder of NGO Écoles du Monde, already established in Madagascar for over 25 years, who wanted to introduce astronomy to children. Écoles du Monde manages the Besely campus, 40 km from Mahajanga, which had the infrastructure needed for astronomical activities.

In 2022, the observatory came to life with the installation of a 34 cm telescope equipped with a camera and a rolling roof, set up by Antoine Cailleau (Astromecca), Sylvain Bouley (SAF), Andoniaina Rajaonarivelo (Haikintana) and the Écoles du Monde team. In June 2022, the International Astronomical Union officially named asteroid "(40201) Besely".

Asteroid (40201) Besely named by the IAU (~5 km diameter, main belt).

Site Infrastructure

The observatory is installed on top of a building on the Besely campus, with an unobstructed view of the sky.

Automated Rolling Roof

Designed by Astromecca, opens automatically to expose the telescope to the sky.

Fibre Optic Connection

Installed by Fondation AXIAN (YAS), enabling remote operation from anywhere in the world.

Solar Power

Solar panels (Fondation EDF) providing full energy autonomy.
