Milkyway@home tries to determine the gravitational potential of the Milky Way. The Milky Way is being investigated because it is the only galaxy that can be captured three-dimensionally from Earth. Through careful study of the movements of the Milky Way components interesting conclusions can be drawn not only with regard to the development of the Milky Way, but also with regard to the origin of the universe. Also, information about the so-called dark matter can be found.

Normally you can only see the apparent location and direction of a star or a galaxy. In our case, we observe the Sagittarius dwarf galaxy, a small galaxy that unites with the Milky Way. Due to the much smaller mass of the galaxy, it is torn apart, pulling an elongated tail of stars and debris behind it. From this it can be calculated where the original location of each star was. With this unique investigation, the gravitational potential of the Milky Way should be studied.

The project is being carried out by the Rensselaer Computer Science Department in Troy, New York. A detailed description in English of the research objective can be found in the forum of the project.

Since new work units (wus) are based on previous results, the project sends a maximum of 20 wus to each machine. A wu currently takes about 2-5 hours on an AMD X2 4200+. The deadline of the wu is quite short with only 3 days. In addition, there are OSX optimized applications that must be copied by hand and are not officially supported by the RPI. Since 20.11.2008 there are official optimized clients.

For donated computation time, so-called badges are awarded [1]: see the badges overview
