The observational capabilities of modern astrophysics are continually expanding. These range from optical telescopes and space telescopes in the infrared to radio telescopes, and from gravitational wave detectors to neutrino observatories. While some focus on light in space, others examine the smallest particles underwater or measure disturbances in spacetime smaller than the diameter of a proton.

This book offers an exciting and comprehensive overview of our technical abilities to explore the universe. It is equally suitable as a foundation for a lecture in astronomy or astrophysics as well as for reading by those interested in the physical sciences.
