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 ...

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 using data from the Dark Energy Spectroscopic Instrument (DESI) have identified some of the clearest evidence yet ...

3I/Atlas might have flown by Earth with its closest approach, but it is still doing things that have people totally enamoured. Yes, indeed, 3I/ATLAS has caused chaotic debates online once again, with ...

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

Researchers found radio telescopes have unknowingly surveyed millions of additional stars, revealing the search for alien civilisations has been broader than scientists realised.

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

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.

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 ...
