A new window for detecting the universe--the 2002 Nobel prize for physics

The pioneering contributions to X-ray astronomy made by Riccaedo Giacconi who won the 2002 Nobel Prize for Physics are described, with emphasis on his extensive observations of the X-ray universe and development of X-ray imaging. The relationship between the advancement of astrophysics and the development of X-ray space observation is pointed out. The concepts of universal dark matter, binary accretion and X-ray jets are also presented. Finally, the outlook for high energy astrophysics is discussed.
