The first time that you gaze up into the night sky and feel the wonder of the universe is the time when most individuals, even the most venerated professional astronomers, think back to when they think about their initial interest in the stars. It is normally a very extraordinary moment, when an adult took you by the hand, pointed at the stars and said: ‘Look, that is the Pole Star’.
Country people will probably discover the night sky earlier than city dwellers because the atmosphere above a city is normally so polluted that you cannot see the stars from below. There are two types of pollutants that prevent you from seeing the stars in a city, smoke and light. Street lights give off a corona that stops you from seeing the weaker light from the stars behind.
If you want to bring back that instant in your life, why not take a child out into the country to look at the stars one night? If you have a pair of binoculars, so much the better, but they are not vital. If you have forgotten which stars are which, get a book on the topic or a map of the night sky. Nowadays you can download a map of the night’s sky for the day that you would like.
The night sky really changes each night. The stars and the constellations do not move much, so you should not have too much trouble finding them, but if a planet is passing by, it will be in another part of the sky each night, which is why it is helpful to have an up-to-date map of the night sky for the date you want to go star gazing.
One of the hardest concepts for a child (or anyone else for that matter to comprehend is the scale of the universe – the sheer size of it. Here are a couple of facts that will amaze most individuals:
1] Our Sun is a star in the galaxy known as the Milky Way and it has its own planets revolving around it. However, there are likely to be 100,000,000,000 (one hundred billion) stars similar to our Sun in the Milky Way.
2] The Milky Way is one of approximately tens of billions of galaxies in the universe and the Milky Way is one of the smaller galaxies.
3] It would take over 100,000 years to get from one edge of the Milky Way to the other, if you were going at more than five trillion miles per year or more than 570 billion miles per hour.
4] It has been calculated that our Milky Way is 14,000,000,000 (fourteen billion) years old
It is very hard to comprehend astronomical numbers like this but this might help:
1 billion seconds ago, it was 1980
1 billion minutes ago, Jesus had only just passed away
1 billion hours ago, mankind was not yet on the planet
