Adaptive optics is one of the major challenges that the future extremely large telescopes face, and it’s essential to reach their scientific goals in terms of accuracy and sensitivity. It’s crucial for the entire scientific community working on the topic to gather and share ideas about the latest advances in this field. This is achieved through the Adaptive Optics for Extremely Large Telescopes (AO4ELT) conference, which has been held every two years since 2009. After the success of the seventh AO4ELT conference organised by the Optics Department of ONERA (the French aerospace lab) and the Marseille Astrophysics Laboratory, the Optoelectronics Laboratory (OPTOLAB) and Pontifical Catholic University of Valparaiso (PUCV) have joined the AO4ELT organisation to host the eighth conference in the series (AO4ELT8). The event was held in the city of Viña del Mar, Chile, between 27 and 31 October 2025.
