This chapter provides a general overview on the main astronomical observations of black holes in the Universe and on their interpretation. We briefly review the spectral state classification, the AGN classification, and the leading techniques for measuring black hole spins (continuum-fitting method and X-ray reflection spectroscopy). We also introduce quasi-periodic oscillations, the possible detection of the shadow of black holes, and the observations and the theoretical models of jets.
