A new study adds to a growing body of evidence that suggests asteroid impacts played a critical role in the emergence of life on our planet.
The microbes "proved very hard to kill."
Tardigrades are practically invincible on Earth, so scientists looked to outer space in search of their kryptonite.
Jupiter's icy Moon is one of the most promising places to search for life in the solar system.
Not even the strongest microbes can survive volcanic eruptions, but they are capable of returning surprisingly quickly, according to a new study.
For more than a decade, scientists have accepted that Titan, Saturn’s biggest moon, has a subsurface ocean of liquid water. A new look at the data suggests otherwise.
18 years ago, a sneaky bacteria infiltrated some of the cleanest places on Earth. Scientists finally know how.
“It is a powerful reminder that life is far more resilient than we often imagine.”
A machine-learning-enhanced approach to chemical analysis is drastically expanding the chemical record of life on Earth, and it could help us find evidence of life on other planets too.
The findings strengthen the case for this icy moon’s habitability.
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.
Alien life could exist on hot, rocky planets, sustained not by water but by a type of salty fluid, new research suggests.
Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests.
The presence of apparent biological signatures on Venus has left UK-based researchers chasing down bacterial life in the planet's clouds.
Dimethyl sulfide is cool—and a potential biosignature—but scientists are urging caution before we declare a plankton party some 120 light-years away.
New JWST data strengthens earlier hints that K2-18b, a possible water world 120 light-years away, could host the chemical byproducts of life.
Researchers exposed two lichen species to Mars-like atmospheric conditions for five hours—and one performed impressively.
The icy moon Miranda is the latest satellite in our solar system to spark hope in the search for life beyond Earth.
The signal, recorded in 1977, was at first suspected to be an alien transmission.
NASA's Perseverance rover has stumbled upon an intriguing rock—one that suggests Mars was once capable of hosting microbial life.
