The "Cambridge Workshops on Cool Stars, Stellar Systems and the Sun" are held biennially and have evolved to be the premier conference series for cool star research.
Sunday Event and Welcome Reception
Join us for a special reception beneath a glowing Earth! The reception will take place under the iconic Geo-Cosmos at Miraikan, one of Japan's leading science museums dedicated to exploring the frontiers of science and the future of our planet. Made of 10,362 LED panels displaying real-time scientific data and satellite imagery of the Earth, Geo-Cosmos provides a striking setting for conversation and networking among participants.
Before the reception, we will hold a talk event at Miraikan Hall. The broad theme of the event is how collaboration between astronomy and various proxies has contributed to our understanding of solar and stellar activity, and possibly climate as well.
