The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.
Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?
For 21 years, the SETI@home project tapped personal computers to analyze unusual radio signals from space.
As this interstellar object approached its closest point to Earth, a massive radio telescope attempted to sniff out a technosignature.
Daniel Whiteson and Andy Warner’s upcoming book is a philosophical exploration of the humanity behind our desire to find aliens.
An astrophysicist has proposed an intriguing explanation for why humanity has never made contact with an extraterrestrial civilization.
In this excerpt from his new book, John Gertz argues it’s time to ditch SETI’s old dogmas and rethink how we prepare for first contact.
We might find intelligent aliens by looking for them the same way they’d find us.
Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests.
3I/ATLAS is likely a comet from a faraway place. Or is it?
If intelligent life exists beyond Earth, these beings may already know where we live.
Seems unintuitive, but the mounting list of lifeless planets might be exactly what scientists need to figure out how common life is in the universe.
In a theoretical study, researchers explored how a twin Earth with human-like life and technology might detect our technosignatures.
"A Sign in Space" simulated an extraterrestrial communication to see whether humans are prepared for the real deal.
Comet C/2023 A3 (Tsuchinan-Atlas) won't be this close to Earth again for over 80,000 years, assuming it survives its approach to the Sun.
A collaboration of several institutions used a remote radio telescope in Australia to listen for signals from extraterrestrials in distant galaxies.
Red dwarfs, the universe's most abundant stars and potential hosts for life-sustaining exoplanets, might actually hinder life due to their severe UV flares, new research suggests.
A new SETI technique, combining game theory, astronomy, and data analysis, aims to locate sites from which alien civilizations might transmit signals.
The generous gift will significantly advance the SETI Institute’s quest to detect intelligence beyond Earth.
With laser-detecting devices in California and Hawaii, SETI researchers will be able to scan an unprecedented amount of sky.
