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

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...

Scientists say the findings of the new study may make future searches for extraterrestrial intelligence faster and more ...

Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that ...

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.

If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...

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 ...
