Abstract
On September 14, 2015, gravitational waves (GWs) were detected by the LIGO (Laser Interferometer gravitational-wave observatory) detectors in USA. The event (GW150914) is originated from a coalescence of two black holes (BHs) located at 13 billion light years away from the Earth. This is the first direct detection of GWs and the first observation of a BH-BH binary. We overview astrophysical sources that can be detected by km-scale laser interferometers on Earth, summarize astrophysical implications of GW150914, and discuss how to explore a Universe with GWs.
