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]
