The LIGO Scientific Collaboration and the Virgo Collaboration identify a second gravitational wave event

While the detection of the waves was announced in February, scientists still don't know exactly where the waves are coming from

"Detecting this signal is possible if we are able to monitor a sufficiently large number of pulsars spread across the sky," says lead author of paper.

Move will significantly improve the ability of scientists to pinpoint the sources of gravitational waves and analyze the signals

LIGO opens new window on the universe with observation of gravitational waves from colliding black holes

Although the waves have yet to be detected, research is intensifying and researchers believe they are close to detecting them
