Constellations

Оглавление

A word worth defining before we launch ourselves into space is constellation. It’s based on a word from Latin meaning ‘group of stars’. In total you’ll find 88 of them filling the entire sky, but thankfully you don’t need to know them all to enjoy the hours of darkness. Other starry terms that crop up throughout the book are written in bold and explained in the AstroGlossary in here.

The story of organising things up there in the darkness of the night began thousands of years ago with civilisations such as the Sumerians, Babylonians, Egyptians, Greeks and Romans (as well as many other cultures from around the world). They decided the starry skies could do with a bit of order and a tidy up. So they joined up many of the stars, just like a dot-to-dot picture, putting their myths and legends into the sky as they did so.

Don’t think that there was any rhyme or reason for making a particular pattern. For example, Cepheus, King of Ethiopia, and his wife, Queen Cassiopeia, both have constellations named after them, and yet these look like a house and a set of stairs respectively. Imagination is the key here, I feel. As far as these early civilisations were concerned, the gods and goddesses needed a place to reside in the starry vault, so it was probably a case of first come, first served, and pot luck as to which stars were assigned to which group.

We get our earliest knowledge of the constellations from Aratos, the first Greek astronomical poet, in his work Phaenomena (which was probably based on an earlier ‘lost’ work by another Greek, Eudoxus). Then in AD 150 Ptolemy, a Greek working at the great library of Alexandria in Egypt, recorded them in a book known by its Arabic name, Almagest, which means ‘the greatest’. Hundreds of years ago, other astronomers who wanted to be famous added extra groups (some more successfully than others) to give us our present fixed total of 88 constellations.

Constellation names are traditionally written in Latin. This is because Ptolemy’s book was brought from the Middle East to Italy, where it was translated – and Latin, for centuries, was the language of scholars. So, for example, we know the Great Bear as Ursa Major.

Here are all the 88 constellations of the starry skies. Details of those with interesting things to see are given in Parts 2 and 3.
