The Cherenkov Telescope Array Observatory (CTAO) will be the world’s largest and most sensitive instrument for the detection of gamma rays and the first open observatory of its kind, making our data from unique, high-energy astronomical observations accessible to all. The CTAO is in the process of becoming an ERIC (European Research Infrastructure Consortium), and the official start of construction on our two array sites in La Palma (Spain) and Paranal (Chile) is on the horizon. In this talk, we will present some of the international outreach and education programmes that are being deployed by the CTAO Outreach, Education and Communication Office during this exciting time.

We will present the educational programme, with a focus on the “Physicist On-Call” project to bring astronomy into the classroom. We will discuss the use of environmentally-friendly online communication and outreach tools, such as the Virtual Tour of CTAO-North, the CTAO array site on La Palma (Spain), and the CTAO virtual exhibit environment, used in science and technology conferences. Finally, we will delve into the “Astrodiversity Project,” which includes guidelines for colour-blind friendly material, the “Women of CTA” event and “Building from Diversity,” a monthly series of articles that features leading figures from underrepresented groups in science.
