Educated in Northern Ireland and at Leicester University where he studied physics, chemistry and astronomy. He did postgraduate work at the University of Cambridge but left to become a science writer. He has written 36 books and over 1,000 articles on astronomy and space many of them in collaboration with Heather Couper. Previously he has been Astronomy Consultant to New Scientist magazine, editor of the Journal of the British Astronomical Association and media consultant to the Royal Greenwich Observatory. Along with Couper and Stuart Carter, director of the Channel 4 series The Stars he set up Pioneer Productions and now develops ideas and proposals for that company.
I read the 1993 edition. The book is oversize with 448 pages, so there is a lot of material, a lot of illustrations. The writing is very accessible, aimed at 5th grade to high school. It is not detailed enough in the science to be much more than a very general reference tool. The illustrations are high quality, useful and clear; if you're looking for detailed pictures, also try The Ultimate Visual Dictionary, which has probably the best pictures you can find for a reference book of this type.
