NEUTRINO NOBEL Arthur McDonald (left) and Takaaki Kajita shared the Nobel Prize in physics for the discovery that neutrinos oscillate between different types, which demonstrates that the particles have mass.

MAGNIFYING THE COSMOS The light from a distant galaxy (lower right) is warped by the gravity of a closer, massive galaxy (bright blur in center).
Experiments probing the secrets of neutrinos, including at the Super-Kamiokande detector in Japan (shown), earned the 2015 Nobel Prize in physics.
The discovery that subatomic particles called neutrinos have mass has won Takaaki Kajita of the University of Tokyo and Arthur McDonald of Queen’s University in Kingston, Canada, the 2015 Nobel Prize in physics.
