Comparative study of two solar eclipses in the 21st century
... Solar eclipses have been seen as incredible events since thousands of years ago. Anyway, they have also been considered terrifying because our ancestors couldn’t understand why the sun disappeared for some hours. For that reason, it was understandable to consider that their gods were sending them a ...
