Tens of thousands of home computers, a fraction of their time and computing power donated by volunteers just like you, are aiding scientists in a massive effort to map the Milky Way galaxy.
Specifically, the MilkyWay@Home project seeks to create a highly accurate three dimensional model of the Milky Way galaxy using data gathered by the Sloan Digital Sky Survey.
Imagine a future Google Earth for the entire Milky Way.
In all, since the beginning of the project, more than 45,000 individuals from 169 countries have donated computer power, with some 17,000 currently active contributors.

Fascinating!
