    Giovanni Domenico Cassini fue un astrónomo, geodesta e ingeniero francés de origen italiano. Tras cuarenta años de observar el cielo, quedó completamente ciego. Midió los períodos de revolución de Marte y Júpiter y descubrió cuatro satélites de Saturno, descubrió la división de los anillos de Saturno que lleva su nombre, Observó el movimiento de los cometas y el movimiento aparente del Sol, descubrió los cambios estacionales de Marte y midió su período de rotación, así como el de Saturno.

    Jean-Dominique Cassini aka Giovanni Domenico Cassini (1625-1712). An Italian astronomer who became director of the Paris Observatory and a naturalized Frenchman. For his early observations of Saturn's rings and moons NASA named its Cassini mission to Saturn in his honor. Cassini is still taking fabulous pictures of the Saturnian system.

NASA's Cassini spacecraft has been studying Saturn and its moons since it entered orbit in 2004. This image, taken on Oct. 5, 2008, is a stunning mosaic of the geologically active Enceladus after a Cassini flyby.

Saturn’s moon Iapetus photographed by the Cassini spacecraft. The right side is overexposed because it’s illuminated by the Sun. The left side glows by light reflecting off Saturn’s clouds. Since sunlight is much fainter at Saturn’s distance than at Earth’s, Cassini had to make a long time exposure to capture this image. (Credit: NASA) Mona Evans, "Earthshine" www.bellaonline.c...
