Anna and Kate lay on the grass looking up at the night sky.'When I was younger' said Anna I used to think that the stars were tiny holes in the sky, where the light shone through from the other side. Now I know that they are huge bright things. Some of them are much larger than the sun. The light that we see left them a long time ago, because they are many light-years away
'I like looking at the patterns they make, and trying to recognize the different constellations' said Kate. 'I visited an observatory with my father earlier this year. We were given a booklet with pictures of the most famous ones. I think I would like to study astronomy when I grow up, and learn about all the different planets and galaxies!
'I wonder how big the universe really is!' said Anna 'Scientists say that it is getting bigger and bigger all the time, but...' 'Wow,what was that?'cried Kate,interrupting her friend.'I just saw a flash of light moving across the sky, much faster than an aeroplane! ' It was probably a meteor! said Anna ' If we watch carefully, we may see some more!
