Astronomy

The origin of astronomy begins around 5000 BC.

-Antonio Abetti was an Italian astronomer (1846-1928).Abetti mainly worked in positional astronomy and made many observations of minor planets, comets, and star occultations. In 1874 he was part of an expedition led by Pietro Tacchini to observe a transit of Venus with a spectroscope. Later he became director of the Osservatorio Astrofisico di Arcetri and a professor at the University of Florence. He refurbished the observatory at Arcetri by installing a new telescope.

-Astronomy took another great leap with Gallileo.

-Astronomy was advanced by Copernicus (1473-1543). He wrote that the Earth orbits the Sun.
