Giordano Bruno (1548 1600), born Filippo Bruno, was an Italian Dominican friar, philosopher, mathematician, poet, and astrologer. He is remembered for his cosmological theories, which conceptually extended the then novel Copernican model. He proposed that the stars were just distant suns surrounded by their own exo-planets and raised the possibility that these planets could even foster life of their own (a philosophical position known as cosmic pluralism)
