The Hypercube

Use your mouse to look around and up and down.

The Universe is very big, so if we try to draw a map of it we would have to use a very small scale. The trouble is, such a map doesn't show any of the beautiful stars, galaxies or planets up there: it's just billions of points of light. To represent these objects, astronomers need to use several different scales. We know more about things closer to us, so the scale gets smaller with increasing distance: as we look further away, we can see a larger area, but in less detail. A scale which varies like this is called a logarithmic scale.

Armagh Astropark's "Hyper-Cube" illustrates the concept of logarithmic scale using a series of nested cubes, each with sides ten times longer than the cube inside:
