   from the simgalaxy dept.
   An anonymous reader writes "Scientists at the University of Zurich
   predict that our galaxy is filled with a quadrillion clouds of dark
   matter with the mass of the Earth and size of the solar system. The
   results in this weeks journal [1]Nature, also covered in [2]Astronomy
   magazine, were made using a six month calculation on hundreds of
   processors of a self-built supercomputer, [3]the zBox. This novel
   machine is a high density cube of processors cooled by a central
   airflow system. I like the initial [4]back of an envelope design.
   Apparently, one of these ghostly dark matter haloes passes through the
   solar system every few thousand years leaving a trail of high energy
   gamma ray photons."
