The Big Bang

The Big Bang is the explanation for how the Universe started.

Astronomers think that everything started in a single point. Then everything expanded and stretched to grow into the huge Universe we see today.

The Universe

Cosmology is the study of the Universe. It doesn't look at small objects, like stars or planets. It investigates the Universe on a large scale.

Many, many galaxies against a black background. Some are tiny dots, and they range in size all the way up to small spheres or swirls. They have different shapes, some more spiraled than others, whilst some appear like smudged lines. They range in colour from red, orange, white, green, and blue.
