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 ...

Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...

Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...

Archived radio observations could open new frequencies to SETI while showing that past searches covered millions more stars ...

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.

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A transmission from a planet may begin as a tightly collimated narrowband signal (left), but after exposure to electrons and ...

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 ...
