Deep below the surface of Antarctica, scientists are hunting for ghosts. Tiny particles called "neutrinos" fill the universe, but they're almost impossible to detect. Their mysterious origins have eluded researchers for decades.

Now, in a discovery that heralds a “new era” of neutrino research, physicists have finally pinned down a source. Researchers probing a huge cube of ice at the South Pole think a violent "blazar" galaxy is churning out the stealthy specks. They reported their results in two papers published in the journal Science.
