[Night-sky jewels]: Ursa Major

Good day to you all!
I’ve decided to talk about the beautifulness of space.
I wish to write about all of the most characteristic and known things you can see in a clear night.

Let’s start today with the Ursa Major
The Ursa Major, also known as the Great Bear, is a constellation visible throughout the year in most of the northern hemisphere. It can be seen best in the month of April

This constellation is clearly visible in the night sky and therefore it has been used for a very long time and it inspired countless myths and legends; from ancient Rome to Finland, from native Americans to South Korea, and a lot more.

The first known observation of it goes back to ancient Egipt.
Astronomy in fact was very important at the time; it was used to decides religious festivities dates and to count night hours.
The Ursa major was one of the constellations used in 2000 AD to make stellar clocks.
