Radio waves from Earth have been moving through space for more than a century. They did not start as part of any grand plan to reach the stars. They began quietly, as a new way for humans to speak ...
December 10, 2025, Mountain View, CA -- For 10 months, a SETI Institute–led team watched pulsar PSR J0332+5434 (also called B0329+54) to study how its radio signal "twinkles" as it passes through gas ...
Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams ...
