8B Neutrinos

8B neutrinos are a type of nearly massless, tiny particles produced in the Sun’s core during nuclear fusion, where hydrogen nuclei fuse to form helium. These neutrinos are called "8B" because they originate from the decay of boron-8 nuclei in the Sun’s fusion process. They travel incredibly fast, almost at the speed of light, passing through matter—including Earth—almost undetectably. Studying these neutrinos helps scientists understand the Sun's inner workings and the fundamental properties of particles. Detecting 8B neutrinos is challenging due to their weak interactions, but it provides valuable insights into stellar physics and particle physics.
