New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder to detect.

Add Yahoo as a preferred source to see more of our stories on Google. However, no confirmed technosignatures like artificial radio transmissions, laser flashes, or excess heat from large-scale alien ...

For more than six decades, astronomers have listened for possible signals from extraterrestrial civilisations, with no confirmed detection to date. A new statistical study considers a narrower and ...

For decades, scientists have been actively searching for signs of extraterrestrial life. Fromradio waves to laser flashes and infrared heat signatures, the hunt for alien technosignatures has ...

A recent SETI Institute study suggests that space weather could blur and weaken extraterrestrial radio signals long before they reach us.

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This is what a recent study published in The ...

For over two decades, millions of people volunteered the computational capacity of their computers to help UC Berkeley scientists in their search for extraterrestrial intelligence (SETI). The goal of ...

If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...
