SETI Signals

The Search for Extraterrestrial Intelligence (SETI) involves scanning the cosmos for artificial signals, such as narrow-band radio waves, that could indicate technology. While most detected signals have natural explanations, a few, like the famous "Wow! signal," remain unexplained. These tantalizing anomalies fuel the possibility that an advanced civilization might be intentionally or accidentally transmitting evidence of its existence, making SETI a ongoing scientific effort to find proof we are not alone.
