Recent research suggests that galaxies with high radio emissions—known as “radio-bright” galaxies—could be home to alien civilizations. This idea, explored in Brian C. Lacki’s study Artificial ...

Solar winds and coronal mass ejections may scatter narrow signals, making them harder for Earth-based telescopes to detect. The SETI Institute uses radio telescopes to search for signs of intelligent ...
