Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...

Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ...

Could the interstellar object 3I/ATLAS exhibit technosignatures, or signals of alien technology? This is what a recent study published in The Astronomical Journal hopes to address as a team of ...

Astronomers seeking signs of alien life may have been listening to the wrong spectrums, a new study found. The majority of ...

One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien signals entirely, a new study finds. Since the very beginnings of the search ...

An international team of researchers looking for signs of intelligent life in space have used artificial intelligence (AI) to reveal eight promising radio signals in data collected at a U.S.

Most radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.

Louisa Mason, a PhD researcher at the University of Manchester, has used archived data from the Atacama Large ...

Experts stress need for transparency while aiming to prevent premature announcements and protect scientists Alien hunters have released fresh guidelines on how to handle potential signals from ...

A comet from another star system does not arrive every year. That is part of what made 3I/ATLAS so compelling when it appeared in July 2025. It streaked into the Solar System on a path so extreme that ...

A message that will be broadcast into space later in 2002 has been released to scientists worldwide, to test that it can be decoded easily. The researchers who devised the message eventually hope to ...
