Cosmology@Home lets you volunteer your spare computer time (like when your screen saver is on) to help search for the model which best describes our Universe and to find the range of models that agree with available cosmological and particle physics data.
Like ordinary matter, dark matter interacts gravitationally with ordinary matter and radiation. Astronomers study the distribution of dark matter through observing its gravitational effects on ordinary matter in its vicinity and through its gravitational lensing effects on background radiation. The background image shows the bullet cluster, a famous example where the visible matter does not follow the mass distribution.
Combining all the available evidence, dark matter represents about 83% of the matter content of the universe. Read more about dark matter on this web page. Let us know your questions and comments on the message board.

Planck/camb version 2.01
The two Docker-based apps have just been upgraded to 2.01, notably with 1) support for Virtualbox 5.1 and 2) Fixed the "Unknown option: --lpt1" on MAC causing some jobs to fail. 6 Jun 2016, 9:40:05 UTC · Comment
Docker-based applications upgrade
The camb_boinc2docker and planck_param_sims apps are getting an upgrade which should reduce even further the number of failed jobs. Read more about the upgrade in the comments. 31 May 2016, 11:48:40 UTC · Comment

Planck contest finished!
Thanks everyone for participating in the Planck contest! Today we picked the winners, big thanks to the top users MaDdCow, 25000ghz, and Rally1965, and the top team BOINC.Italy, who we will mention in our paper. You, along with the ~2500 other users and ~300 other teams contributed a ton of computing power to allow us to do this analysis over the last several months. 6 May 2016, 0:34:09 UTC · Comment
Planck contest deadline announced
