Question

Quizplus · Accepted Answer

Most SETI searches are done at radio wavelengths because radio waves can penetrate through dust and gas clouds in space, and also because radio telescopes are more sensitive and capable of detecting weak signals from distant sources. In addition, radio emissions are a common and natural form of communication used by many celestial objects, such as stars and pulsars, making them a good target for SETI searches. Most SETI searches are done at radio wavelengths since radio waves can pass through interstellar dust and gas with little interference, allowing for long-range communication signals to be transmitted and received.
