*Last Thursday on February 6 LIGO detected a gravitational wave that originated 1.1 billion light years from the Earth and was caused by either a neutron star neutron star merger or a black hole and neutron star merger; the resulting object was less than five solar masses and possibly less than three. That alone would be interesting because it would be the smallest mass that has ever produced a detectable gravitational wave, but there's more. Less than five minutes after the gravitational wave the IceCube detector in Antarctica saw a burst of neutrinos, and the Chime radio telescope in Canada detected a fast radio burst, neither of those two things had ever been associated with the gravitational wave before. The scientific name for the event is S250206dm.*
