A team of researchers has established that fast radio bursts (FRBs) include radio waves at frequencies lower than ever detected before, a discovery that redraws the boundaries for theoretical ...

THE wireless engineer and radio physicist require to know the speed or velocity of electric waves in order, for example, to convert their measurements of frequency into the corresponding wave-lengths, ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe.They reported Wednesday that they ...

Something’s fishy in the southern constellation Phoenix. Strange radio emissions from a distant galaxy cluster take the shape of a gigantic jellyfish, complete with head and tentacles. Moreover, the ...
