Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space ... “Are those that repeat different from those that don’t? What about the persistent radio emission ...

When the New York Times first wrote about "mysterious radio waves" from the cosmos in 1933, they made sure to note one fundamental caveat: "No Evidence of Interstellar Signaling." Indeed ...

THE coming into operation of the Luxembourg high-power broadcasting-station on a wave-length of 1190 m ... that when a radio-receiver was tuned to Beromünster (460 m.), the modulation of the ...

So, instead of using ultrasound, radio waves are used as they travel at 300,000,000 m/s. It works in the same way as sonar but with radio waves in place of ultrasound. A short pulse of radio waves ...

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...

Fast radio bursts (FRBs) are intense blasts of radio waves that can emit as much energy as the sun puts out in three days — but in just thousandths of a second. Much about these events remains ...
