In science, astronomy is the study of the nature of the movements and behaviors of things in the universe, such as: planets, stars, galaxies, asteroids, comets, blackholes, galactic clusters, galactic filaments, the dark matter problem, the accelerating satellites problem, among other anomalies.

The following are related quotes:

“The first to turn his attention to the problem of investigating the distance and sizes of the stars was Aristarchus, the Samian, who lived four hundred years before Ptolemy and recorded for posterity the theories of Pythagoras. Hipparchus of Rhodes followed him: the Ptolemy, with his magnum opus of five books, Al-Battani and Al-Fargani (c.790-861) (Ѻ)(Ѻ), the Arabs, and more recently Muller (of Konigsberger), Copernicus, Tycho Brahe, Kepler, Wendelin, Lansberg, Riccioli and a number of others.”
