With billions of potentially habitable worlds scattered across the universe, alien civilizations should be out there — yet decades of searching have produced no confirmed contact. From the Fermi ...

For decades, the search for extraterrestrial intelligence has been defined more by silence than discovery, but that balance may be starting to shift. As new telescopes, algorithms, and theoretical ...

Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That ...

For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are dominated by several recurrent tropes. There's the invasion by a warlike ...

For decades, radio SETI searches have focused on one important question: if another technological civilization is trying to contact us, how would they send that message? For Dr. Zuckerman, the ...

We’ve likely had at least one close encounter of the 3I kind before. Harvard scientist Avi Loeb claims that not only does 3I/ATLAS potentially have alien origins, but that this wouldn’t be the first ...

Seventy years ago, Italian-American nuclear physicist Enrico Fermi asked his colleagues a question during a lunchtime conversation. If life is common in our Universe, why can’t we see any evidence of ...

Perhaps what remains at the end of an advanced civilization is not biological, but artificial intelligence...There are ...

"There is a silence in the night sky that has bothered me for as long as I can remember." That line, attributed to Richard Feynman, lands because it gets at a simple, stubborn feeling. The sky looks ...
