Antimatter

Physicists, I suspect, will never really answer the question of why there is something rather than nothing. But in the meantime, they are making remarkable progress on a slightly less vexing mystery: Why is there so much more matter than antimatter in the universe? Check out our lead story to learn more. In other cosmic news, astronomers may have captured the first-ever image of a planet orbiting Proxima Centauri, our solar system’s nearest neighboring star, astrophysicists have detected a never-before-seen configuration of merging black holes, and the countdown continues towards the inaugural launch of astronauts on commercial rockets later this spring.
