This week, my daughter has been thinking about stars: “They’re not just twinkly spots in the sky – they must be made of something,”she says. “But what are they made of? And how did they get up there?”
I was asked two questions a few weeks ago and I’ve been pondering the answers ever since: Why is there no air on the Moon? And how does our air stay on Earth?
These fantastic questions got me thinking about my answers to What is air made of? and Why are there no trees on the Moon?. But neither of those quite answered these new questions. So, after much deliberation, here’s my answer!
Some of us will travel all over the world during our lives and discover lots of countries, habitats, animals, plants and other people; others will stay much closer to home.
But, how big is our world? And how does its size relate to other things in our universe?
The sky is all around us. When you look up at the sky, it can be blue or grey or sometimes pinky orange, and there may be clouds floating along. You might also see birds or insects flying, or aeroplanes or helicopters! But where does the sky start and where does it end?
My daughter asks lots of questions about the Moon: How big is it? Why does it change shape? How bright does it shine? And this is my attempt to answer all of her Moon questions in one go.
But first, I would like to thank my friend Alex for kindly allowing me to use his wonderful photo of the Moon to illustrate this blog post.
My 5-year-old is fascinated by the night sky and loves to look at the moon and stars. She wants to buy a telescope so that she can see all the stars in space! But she wonders why are all the stars white?
Well, they’re not but you can’t see their colours by looking at them with just your eyes. They are so very far away from Earth that you need to use a telescope to study them in more detail.
