GW190425 was a gravitational wave detected[2][3] on 19 April 2019 in LIGO[4] and Virgo[5] interferometer. It was a compact binary coalescence[6][7] with a signal to noise ratio 12.9. It is the result of a collision of two neutron stars or binary stars[8] with a total mass of 3.4 Solar[9] masses[10] (larger than any known binary neutron stars).[11] Its host galaxy is likely UGC 10667.[12]
