Underneath the vast, frozen landscape of the South Pole lies IceCube, a gigantic observatory dedicated to finding ghostly subatomic particles called neutrinos. Neutrinos stream through Earth from all directions, but they are lightweight, abundant and hardly interact with their surroundings. A forthcoming upgrade to the IceCube detector will provide deeper insights into the elusive particles.
By developing clever theories and conducting experiments with particle colliders, telescopes and satellites, physicists have been able to wind the film of the universe back billions of years—and glimpse the details of the very first moments in the history of our cosmic home. Take a (brief) journey through the early history of our cosmos.
Growing up in South Africa, the first language that science writer Sibusiso Biyela learned was Zulu, the most common mother tongue in the country. But the scientific content he consumed as a child—movies, cartoons and documentaries—was in English. Biyela aims to bring science back to South Africa’s Zulu communities.
