This SETI program is chasing down its final 100 signals. Could one of them be from aliens?
SETI@home has been one of the largest citizen science projects ever, with millions of users around the world.
NASA funds new tech for upcoming ‘Super Hubble’ to search for alien life: ‘We intend to move with urgency’
The observatory will combine tech from NASA's most powerful space telescopes.
Jupiter ocean moon Europa likely lacks tectonic activity, reducing its chances for life
New models suggest that Europa has very little tectonic activity at its seafloor, which is potentially catastrophic news for the hopes of finding alien life within its ocean.
How did life begin on Earth? New experiments support ‘RNA world’ hypothesis
The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead of DNA.
Can scientists detect life without knowing what it looks like? Research using machine learning offers a new way
If nonliving materials can produce rich, organized mixtures of organic molecules, then the traditional signs we use to recognize biology may no longer be enough.
We didn’t find answers in 2025, but UFO researchers say the search continues
"Science doesn't always go as planned. In any case, there's a lot of work to be done."
Surprise! Saturn’s huge moon Titan may not have a buried ocean after all
"We're not certain if having widespread liquid pockets instead of a global ocean makes Titan more or less habitable."
Which exoplanet in the TRAPPIST-1 system could be habitable? Scientists are modeling the star to find out
Frequent flares from the nearby star TRAPPIST-1 could offer new clues in the search for habitable planets beyond Earth.
Beyond the habitable zone: Exoplanet atmospheres are the next clue to finding life on planets orbiting distant stars
But being in this sweet spot doesn't automatically mean a planet is hospitable to life.
SETI’s ‘Noah’s Ark’ – a space historian explores how the advent of radio astronomy led to the USSR’s search for extraterrestrial life
An expert dives into the history of radio astronomy and the search for life beyond our Earth.
