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

Researchers from the search for extraterrestrial intelligence (SETI) may have figured out why we have not detected any alien signals as of yet, and it could partly explain the infamous "Fermi paradox" ...

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually ...

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 ...

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.

The odds of there being another intelligent life form in the Milky Way are pretty good given the billions of stars. But we ...

With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we ...

What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This is what a recent study published in The ...

The Fermi paradox asks why we haven’t found aliens yet. Scientists say the answer may lie in timing, technology, and the vast ...

Using emerging radio techniques refined during and after the Second World War, the astronomers detected a powerful radio signal that appeared to originate from beyond the Milky Way. This happened when ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of ...
