CTAO LST sub-Array Inauguration
The inaugural ceremony of the LST sub-Array will take place at the CTAO-North site at the Observatorio del Roque de los Muchachos (ORM) on La Palma, Canary Islands, on Thursday, October 15, 2026.
This event marks a significant milestone in establishing the Cherenkov Telescope Array Observatory (CTAO) and celebrates the completion of the LST sub-array, which includes four 23-meter telescopes built through an international effort involving more than 500 scientists and engineers from over ten countries. These 23-meter-diameter telescopes play a key role in the observatory’s scientific mission, enabling groundbreaking observations of the Deep, Dark, and Extreme Universe in high-energy gamma rays.
The inauguration will bring together representatives from the CTAO Central Organization, the CTAO Consortium, the Instituto de Astrofísica de Canarias (IAC), participating universities and research institutions, as well as the funding agencies and industry partners who have made this achievement possible, along with well-respected scientists. The ceremony will also provide an opportunity to recognize the exceptional dedication of the teams who have worked for more than a decade to bring the LST Project to completion.
