When I first became interested in Astronomy, the non-visual part of the spectrum held little interest for me. The charts and graphs representing radio waves received from distant objects were unexciting compared to the drama of Saturn's rings or the wispy beauty of the Orion Nebula. This has changed thanks to the new computer generated ways of displaying non-visual data.
Every page is illustrated with one or more full color photographs.
The authors have wisely decided to introduce each new major section of the electromagnetic spectrum with a description of the technology used to explore it and what objects its most suited to. There is no mathematics required but the reader should have some familiarity with the idea of wave lengths, stellar evolution and galaxies.
