Construction and commissioning of the second-generation Advanced LIGO and Advanced Virgo gravitational-wave observatories continues on schedule. We expect the first observing run to occur later this year. The primary observational target for these interferometric detectors is the merger of two compact objects neutron stars and/or black holes. In this talk we will focus on the science that observations of such compact binary mergers will enable. We will start by briefly discussing the methods by which we hope to observe such mergers. Then we will discuss how often we expect to make such observations and what we can learn from individual observations of compact mergers. How well will we measure the properties (component masses, spins, sky location etc.) of a compact binary merger? We will also discuss what we can learn from populations of compact binary merger observations with gravitational-wave facilities and describe the potential for jointly observing sources with both gravitational-wave and electromagnetic observatories. The next few years should be a very exciting time for the field of gravitational-wave astronomy!
