These are always images that mark the minds of young and old.explains Arnaud Leroy, president of the Uranoscope of Île-de-France, which organizes an evening of observation of the night sky, Saturday August 6th.

For those who do not have equipment or cannot move around the observatories, a star gazing is available on the AFA website. “in order to make observation accessible to all”.
