Could it be that dark matter "halos"—the huge, invisible cocoons of mass that envelop entire galaxies and account for most of the matter in the universe—aren't completely dark after all but contain a small number of stars? Astronomers from UCLA, UC Irvine and elsewhere make a case for that in the Oct. 25 issue of the journal Nature.
