At the age of 76, Masatoshi Koshiba, a Japanese physicist who laid the groundwork for neutrino astronomy, was recognized for his groundbreaking contributions to experimental particle physics, primarily for the detection of cosmic neutrinos as part of the Kamiokande-II experiment that he led. This remarkable achievement solidified his legacy and led to him being jointly awarded the Nobel Prize in Physics in 2002 alongside Raymond Davis Jr. and Riccardo Giacconi.
