Nearly two decades ago, an experiment floating high above Antarctica caught a weird signal. The balloon-borne suite of instruments recorded a similar event in 2014, and scientists have been scratching ...

Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as ...

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 ...

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

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio ...

It may sound like a plot twist out of a science fiction novel, but researchers have detected mysterious radio signals coming from beneath the Antarctic ice that appear to be inconsistent with the ...

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...

A new study from Tel Aviv University has predicted, for the first time, the groundbreaking results that can be obtained from detecting radio waves coming to us from the early Universe. The findings ...
