Although the theoretical background predicting gravitational waves has been known for over a hundred years, we can detect them only relatively recently. Several such detectors operate worldwide, collecting datasets from about a hundred events produced by merging stellar-size compact objects. The catastrophic events leading to the detectable gravity wave emissions occur at cosmological distances and are the most energetic processes in the universe. They perform the significant pieces to the puzzle of multimessenger astronomy; in some cases can be identified with a source of electromagnetic radiation which enables their precise localization and observational confirmation of other essential characteristics. In any case, gravity wave astrophysics is a challenging and fastly developing field of modern science.
