        Hunting Solar Neutrinos

        For almost four decades, astrophysicist John Bahcall and chemist Raymond Davis Jr. struggled to solve a nagging and important mystery in particle physics: How many neutrinos does the sun produce, and how many reach the Earth? The answer would shed light on how stars like our sun produce energy. Bahcall, who died in August 2005 at age 70, reflects on his career-long and eventually successful quest in this interview from NOVA Online.
