Astronomy for GCSE has guided many students through the astronomical material in the National Curriculum since it was first published in 1990. It is now reissued in a second, updated edition, incorporating new chapters on cosmology, non-optical observing and spectrosopy, to take account of the latest modifications to the GCSE syllabus. The questions at the end of each chapter and recommended practical work have both been modified to fit in with the modern style of examination, and the text has been updated to take account of missions such as Magellan and Galileo, results from the Hubble Space Telescope, and the many other exciting developments of the last ten years. Several new NASA photographs are included.
