It is one of the cosmos’ most mysterious unsolved cases: dark matter. It is supposedly what holds the universe together. We can’t see it, but scientists are pretty sure it’s out there.

Led by a dogged, Nobel Prize-winning gumshoe who has spent 18 years on the case, scientists put a $2 billion detector aboard the International Space Station to try to track down the stuff. And after two years, the first evidence came in Wednesday: tantalizing cosmic footprints that seem to have been left by dark matter.

But the evidence isn’t enough to declare the case closed. The footprints could have come from another, more conventional suspect: a pulsar, or a rotating, radiation-emitting star.
