The Group of Relativity and Gravitation at the University of the Balearic Islands participates through the LIGO Scientific Collaboration in identifying a second event of gravitational waves in data-LIGO detectors Advanced.

On December 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves — ripples in the fabric of spacetime — for the second time. The gravitational waves were detected by both of the twin Laser Interferometer Gravitational – Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA.
