Astronomy is perhaps the oldest of sciences yet continues to be a thriving area of scientific investigation. Scarcely a week passes without some news item regarding a new astronomical discovery or event. The development of techniques such as spectroscopy and photography in the nineteenth century led to the application of Physics to the analysis of astronomical information - Astrophysics became a scientific discipline. The twentieth century saw a dramatic developments in technology that allowed astronomers to finally start investigating all parts of the electromagnetic spectrum. Already the new century has seen exciting discoveries and new technologies come into more widespread use. The future of astrophysical research is bound to be just as enthralling and challenging as the past.
