The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant intelligent life. Now researchers believe that space weather could distort and blur s ...

Solar storms around distant stars may be erasing alien radio signals before we ever hear them In A Nutshell Stellar winds and ...

Associate Professor of Physics Jonathan Pober has spent the past 20 years detecting faint astronomical signals in radio waves that can provide information about the early universe. This task can be ...

A team of UC Berkeley scientists has painstakingly analyzed billions of radio signals received over fifteen years and have zeroed in on 100 that are most likely to be sent by extraterrestrial ...

Penn Engineers have developed a system that lets robots see around corners using radio waves processed by AI, a capability ...

A new open-source project, WiFi DensePose, uses ordinary WiFi signals to detect human movement behind walls without cameras. The system analyzes subtle signal changes to create a digital skeleton of ...
