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 ...

Yet the key insight lies not in what was found, but in what the analysis revealed about the scale of previous searches.

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced ...

Astronomers have unknowingly listened in on more than 6.1 million stars during previous searches for alien signals, according ...

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.

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

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

Every November, the Leonid meteor shower lights up the sky — a dazzling reminder that our planet is just one small part of a vast, mysterious cosmos. As shooting stars streak overhead, it's hard not ...
