There is a particular kind of quiet that settles over an astronomer's control room after a long night of listening to the sky ...

Given the size and age of the universe, it should be full of species with technology far more advanced than our own. But so far there is no trace ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more natural source. In a series of papers, astronomers have compared the "Wow!

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

The scientist, professor Matthew Bailes of Swinburne University of Melbourne, spoke about how he was excited when he learned he was going to take the lead of part of the Breakthrough Prize ...
