AstroSim: Collaborative Visualization of an Astrophysics Simulation in Second Life

Developed in the Second Life 3D online multiuser environment, AstroSim (astrophysics simulation) provides synchronous collaborative visualization for astronomers. Users can play, halt, and rewind simulations and annotate stars interactively to track individual stars and gain a better understanding of stellar dynamics and astrophysics phenomena. This article is part of a special issue on collaborative visualization.
