A satellite image is a picture of the Earth taken from a thing called a satellite – that's like a really big machine in space that helps us see things on the ground from far away. It's like when you look at your toy from far away and can still see what it looks like.
The satellite takes a picture from way up high in the sky and it captures everything it sees below it – like the trees, buildings, roads, and even the clouds! Just like how you take a picture with a camera, the satellite does the same thing, but it's way up high where it can take pictures of really big places.
Scientists use these pictures to learn a lot about the Earth like weather patterns, where to build roads and buildings, and how to help animals by tracking their movements.
So whenever you see a picture of the Earth taken from space, just know that it's a satellite image!
