June 2014 time–lapse photo taken by Shane Larson of sky over Smart Hall at the Aspen Center for Physics during an astrophysics workshop.

"The atmosphere at ACP is inspiring and my creativity level seems to go up as if I were in my twenties. The staff here is professional and very friendly. The facilities are perfect. The talks here are excellent...Being in Korea, I often find myself isolated from the frontline of research. Staying here at ACP helps me to be in contact with a world-class level of research and gives me an opportunity to meet people who are actively involved in the hot issues of my interest."
