Sharing knowledge is a fundamental mission of the Observatoire de Paris-PSL. All our staff are committed to making scientific advances accessible, and to promoting a scientific culture and a critical mindset among different audiences. We implement a wide range of actions to give everyone access to the expertise of our researchers. The Observatory is also heavily involved in operations specifically designed for schoolchildren, such as class sponsorships, the provision of travelling exhibitions or welcoming pupils during the Fête de la science.
