How do we fit in compared to everything in the Universe? This diagram, created for the children's book Insiders: Space, attempts to enlighten you. It shows the Earth's place in the Solar System, then zooms out to show where the Solar System is locate...

This image shows some of the things that are in the Universe arranged in order of scale – although not actually to scale. In this diagram you can see (bottom left) subatomic particles, an atom, a molecule (of DNA), red blood cells, a human, the Ear...

We see the constellation of Orion as just a 2D projection on the night sky, and it is easy to imagine that all the stars are at the same distance from us. But, as this schematic shows, this is not true. The closest star, Bellatrix, is around 240 ligh...

This image, commissioned for the children's book Insiders: Volcanoes and Earthquakes, shows the inside of our planet. The outermost layer is the crust; the outer mantle (dark orange) in beneath that, then the lower mantle (light orange); finally ther...

Pulsars are like cosmic lighthouses. This image was done to show how a pulsar actually works. Radiation comes out of the cones. The whole thing spins on its axis, often several times a second. Then, if the Earth is in the line of sight of the radiati...

This is what you'd find inside the Sun and other stars like it. The centre is the core, where the Sun produces energy from nuclear reactions. Next is the radiative zone, where the radiation streams outwards. Then in the convective zone, the radiation...

Stars come in many sizes and colours, as this diagram for my ...
