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 ...

A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The thought experiment suggests that we need to avoid human biases in our ...

In the vastMilky Way, billions of planets may harbor life, but new research presented at the EPSC-DPS2025 Joint Meeting suggests that alien civilizations capable of communication are likely rare. Led ...

Major airports may be alerting intelligent alien civilizations to our presence, according to new research. Are we being watched? Radar systems at major airports may be doing more than managing air ...

Earth may already be broadcasting its presence to alien civilizations without realizing it. A new study shows that our deep-space transmissions, especially those aimed at Mars and interplanetary ...

The Fermi Paradox ponders an endlessly fascinating question: If so many worlds exist in the universe, why haven’t we detected any sign of extraterrestrial life? A possible reason, called the ...

Technosignatures are theoretical signs of technologically advanced alien civilizations, but so far, none of those civilizations have phoned home. Researchers from the Search for ExtraTerrestrial ...

Complex, intelligent life in the galaxy appears vanishingly rare, with the nearest possible civilization perhaps 33,000 light-years distant. Yet despite the odds, scientists insist that continuing the ...

"I really wanna see the mass driver on the moon that is shooting AI satellites into deep space. Just going like 'shoom, shoom,' just one after the other." ...

Astrobiologists propose that alien civilizations need accessible coal deposits to industrialize exoplanets and become detectable from Earth.
