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

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not recently been explored.

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 ...

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 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 ...

Astronomers might be hunting for alien signals in all the wrong places. A new ...

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 ...

Researchers found radio telescopes have unknowingly surveyed millions of additional stars, revealing the search for alien ...

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.

Below is my ham radio. I have a permit for it, and you're allowed to use it. Adjust the bands and the dials to see if you can make contact with an alien! There are eight alien signals hidden within ...
