A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The ...

Could the first confirmed signal from an extraterrestrial source be less a hello than a goodbye? Astrophysicist David Kipping argues as much, and his “Eschatian Hypothesis” reimagines the way ...

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 ...

In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in ...

If so, why haven’t they said hello? The humble residents of this pale blue dot have been on a quest to find an alien civilisation for more than a century. First, it was the “canals” of Mars. Then ...

After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced ...

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...

The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we might have a chance at detecting their ...

"Although ETIs might be rare, there is only one way to really find out, and that is by searching for it." When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

Earlier this month, astronomers made a fascinating discovery: a mysterious object with interstellar origins, now dubbed 3I/ATLAS, that’s hurtling toward the inner solar system at extreme speeds. As ...

For decades, the search for extraterrestrial intelligence has largely been predicated on a specific assumption: that advanced civilizations will inevitably grow, expanding their energy consumption and ...

What new methods can be used to detect alien technosignatures? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers from Pennsylvania ...
