1267: CERN finds a new particle + News alerts for the cosmos
Researchers at the Large Hadron Collider in Switzerland have announced that they discovered a new subatomic particle. Roughly four times more massive than a standard proton, this short-lived piece of matter called Ξcc⁺(Xi-cc-plus) is like an extra-heavy proton, researchers say. Physicist Hassan Jawahery joins Host Flora Lichtman to unpack how the particle was found, and what its discovery means for theoretical physics. Then, astronomer Eric Bellm describes a new alert system that could flag potentially significant changes in the southern night sky in real time. On its first night of testing…
