摘　　要：The X ray observatories XMM Newton and Chandra provided a wealth of exciting new results. Chandra delivered X ray images of outstanding detail, reaching subarcsecond spatial resolution for the first time in X ray astronomy. XMM Newton provided the highest signal X ray spectra ever taken. The imaging and spectral observations are greatly improving our understanding of the physical processes in the central region of active galaxies. The increased sensitivity also allows to peer into the high redshift universe beyond z=5. I shall provide a review of recent X ray highlights on (radio quiet) AGN from low to high redshift, and exciting questions still open. I conclude with a glimpse into the future of X ray astronomy.The X ray observatories XMM Newton and Chandra provided a wealth of exciting new results.
