  With ~2 Ms of Chandra exposure, the Chandra Deep Field-North (CDF-N) survey
provides the deepest view of the Universe in the 0.5-8.0 keV band. Five hundred
and three (503) X-ray sources are detected down to on-axis 0.5-2.0 keV and 2-8
keV flux limits of ~1.5x10^{-17} erg cm^{-2} s^{-1} and ~1.0x10^{-16} erg
cm^{-2} s^{-1}, respectively. These flux limits correspond to L_{0.5-8.0
keV}~3x10^{41} erg s^{-1} at z=1 and L_{0.5-8.0 keV}~2x10^{43} erg s^{-1} at
z=6; thus this survey is sensitive enough to detect starburst galaxies out to
moderate redshift and Seyfert galaxies out to high redshift. We present the
X-ray observations, describe the broad diversity of X-ray selected sources, and
review the prospects for deeper Chandra exposures.
