First-principles calculations show that strong correlations and interactions between two nucleons slow down beta decays in atomic nuclei compared to what’s expected from the beta decays of free neutrons. This impacts the synthesis of heavy elements and the search for neutrinoless double beta decay. Credit: Andy Sproles/Oak Ridge National Laboratory, U.S. Dept. of Energy

On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole, represented in this illustration by strings of sensors under the ice, detected a high-energy neutrino that appeared to come from deep space. NASA's Fermi Gamma-ray Space Telescope (center left) pinpointed the source as a supermassive black hole in a galaxy about 4 billion light-years away. It is the first high-energy neutrino source identified from outside our galaxy. Credits: NASA/Fermi and Aurore Simonnet, Sonoma State University
