Wrong frequency? Astronomers rethink where to hunt for alien signals
Astronomers might be hunting for alien signals in all the wrong places. A new ...
Louisa Mason's study uses archived ALMA data to explore new radio frequencies for alien signals, expanding SETI's search ...
Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...
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.
Most radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.
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.
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 ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
