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 searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...
Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
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 radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.
They did not find any; but as PhD researcher Louisa Mason told IFLScience, "My work at the moment is less about looking if aliens are sending messages and more about thinking about how we use these ...
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 ...
Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not ...
A new SETI study argues that turbulent space weather around distant stars can smear out ultra‑narrow alien radio signals, meaning technosignatures may already have reached Earth.
