Summary

Description	English: GW170817 Gravitational Wave Chirp Spectrogram This spectrogram combined the signals from both Hanford and Livingston detectors to show the characteristic sweeping chirp. As the neutron stars came closer to each other, circling faster, they produced higher frequency gravitational waves shown by the greenish line sweeping upwards.
