Analysis of 20 years of NASA antenna operations shows that the most powerful terrestrial radio signals are emitted in the plane of the Solar System. If extraterrestrial civilizations follow the same logic, their transmissions should be sought right there, especially when a planet passes in front of

The Vera Rubin Telescope will discover thousands of interstellar visitors. To tell a natural object from a relic of another civilization, scientists have developed a protocol: they’ll study the light 'fingerprints' of these guests.

Using the OVRO–LWA array, astronomers conducted an unprecedented survey in the 50–86 MHz band with 10 Hz resolution. The 30-second exposure produced over three million images, setting strict limits on the power of hypothetical transmitters around nearby stars. No extraterrestrial signal was detected
