Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as ...
The journey of Earth’s radio signals began over a century ago, following the first intentional broadcast by Reginald Aubrey Fessenden in 1906. These signals have been traveling across the Milky Way ...
An imaginative and compelling book reveals how radio waves help us tune in to our universe – and even search for alien ...
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 ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, ...
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 ...

As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and ...
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 ...
The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...
