"Scientists from around the world have made the first steps in unravelling a hundred year-old mystery—the source of cosmic rays—and U of A researchers are among those to make the discovery.

Using a particle detector at the South Pole, scientists have confirmed high-energy neutrinos (neutral particles) that originate from beyond our solar system.

“This is huge—it could be the start of a new way to look at outer space and objects there,” said Darren Grant assistant professor at the U of A and lead of the IceCube Collaboration effort in Canada. “Until now, we could look at a star and see the surface. With neutrino astronomy, we can see what happens inside that star. That’s the difference. It‘s our next step in studying the universe.”"
