We are in the era of gravitational-wave and multi-messenger astronomy, kick-started by the Advanced LIGO and Advanced Virgo detectors. The Advanced detectors concluded their third observing run in March 2020. The latest catalog of compact binary coalescences from LIGO-Virgo-KAGRA contains 90 events with probability of astrophysical origin greater than 0.5. All events are believed to be mergers of neutron stars or/ and black holes. I will describe the analysis framework used to produce these catalogs and provide a summary of the observations and what we have learned from them. I will conclude by discussing prospects for gravitational-wave science in the coming years.
