Nuits des Etoiles 2025 returns this August. In Paris, head for Square Louise Michel on the night of August 3 to 4, 2025, from 9 p.m. to 1 a.m., for an exceptional evening under the starry sky . To mark the occasion, theAssociation Française d'Astronomie (French Astronomy Association ) invites the curious, young and old alike, to the 18th arrondissement square at the foot of Sacré-Coeur, for several hours of observation of the stars, planets and Milky Way.
At the highest point in the capital, members of the association will provide Parisians with glasses and telescopes turned towards the starry sky, sheltered from the lights in the park, and will alternate between observation sessions and sky-spotting workshops, for a magical evening in Montmartre!
Note that if you miss this evening, other evenings are also organized, as part of the "Paris under the stars" operation and the nocturnal opening of certain Paris parks and gardens. Ideal for observing the Perseids throughout August!
Admission is free and open to all!
