A Neutrino Observatory is a scientific facility designed to detect and study neutrinos, which are tiny, nearly massless particles that rarely interact with matter. These observatories are often located underground or underwater to shield them from other cosmic particles and background noise, allowing for more accurate measurements. Neutrinos are produced in various processes, such as nuclear reactions in the sun, supernovae, and particle accelerators. By studying neutrinos, scientists can gain insights into fundamental questions about the universe, including the nature of dark matter and the processes occurring in stars.
