Detecting Gravitational Waves
Scientists have announced the detection of four new gravitational waves, bringing the total to 11. First captured by the LIGO detectors in 2015, the new observations of ripples in the fabric of space-time are quickly adding up and helping researchers to better understand powerful and distant cosmic phenomena like black holes and neutron stars.

Scientists, using LIGO and the European-based Virgo gravitational wave detectors, have detected gravitational waves
