The Oort cloud is a hypothetical cloud of small icy bodies surrounding the Sun at more than 1000 AU. It is thought to be a vast reservoir of comets that occasionally get disrupted, sending comets t…
Astronomy in other cultures Not only the west looked at the sky. In ancient times, astronomy also developed in other latitudes, both in the East and in the Americas. Studies conducted by paleontologists and anthropologists in different tribes seem to demonstrate the need of primitive societies to keep a record of the events of the sky, in order to obtain knowledge about events such as bird migration stations, recursion of periods menstrual, the need for guidance or influence on animals and plants.
