Mar 16, 2025 · In 1974, humans sent this powerful radio transmission toward a star cluster 25,000 light-years away. The message encoded numbers, chemical formulas, and a stick figure of a human—all in binary, a language of 1s and 0s. If we can do it, so can they. But deciphering an alien message would require more than decoding math.

Feb 19, 2025 · Strange radio signals might be a sign of an artificial transmission from an alien species. But our Milky Way galaxy is swimming in radio emissions of all sorts, from exploding stars to the...

Jan 2, 2025 · Scientists have finally discovered the mysterious origins of an 'alien' signal received from outer space. In 2022, a radio telescope detected a burst of energy coming from a galaxy about 200...

Feb 3, 2023 · An algorithm has detected eight mysterious radio signals that possibly came from aliens. Here are the details.

Nov 11, 2024 · After the ExoMars Trace Gas Orbiter, a European Space Agency spacecraft orbiting Mars, beamed a signal containing an alien-like message in May 2023, three observatories on Earth picked it up and...

Apr 4, 2023 · Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may...

Jan 23, 2025 · For years, researchers have been looking to explain fast radio bursts, or FRBs, which are very short and very powerful blasts energy coming from deep in space. Possible explanations have included...

Feb 7, 2025 · Using a radio telescope, the scientists detected a recurring radio signal from exoplanet YZ Ceti b, located approximately 70.5 trillion miles from Earth. They speculate that these waves could be produced by interactions between the exoplanet's magnetic field and its host star, a small red dwarf named YZ Ceti.

Oct 17, 2024 · As detailed in a study set to be published in The Astronomical Journal, astronomers have developed a method that allows alien hunters to listen for much smaller bandwidth radio signals,...

3 days ago · How Radio Telescopes Search for Alien Life (image credits: unsplash) Radio telescopes like the Parks Radio Telescope are adept at picking up radio waves emitted by celestial bodies. These waves can offer clues about the composition, distance, and movement of objects in space. In the search for extraterrestrial intelligence (SETI), scientists ...
