Wright's theory of the universe. Diagram showing the Earth surrounded by concentric shells of stars, as published in 'An original theory or new hypothesis of the Universe' (1750) by English astronomer Thomas Wright (1711-1786). In this book Wright gave the first explanation of the appearance of the Milky Way as being due to our immersion in a layer of stars. He proposed that the Sun is one of many stars orbiting around a Divine Centre and that the stars are distributed either in annuli (rings) or in thin, concentric, spherical shells (as seen here).
