Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known ...

A new study published in Monthly Notices of the Royal Astronomical Society has pinpointed the best planets for the search for ...

'As the number of exoplanets we've discovered increases, the question about life existing somewhere other than the Earth ...

Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their formation but ours managed to hit. A new study shows that Earth formed under ...

K2-18b resides within the habitable zone of its star, making the presence of liquid water and thus life possible. Using the James Webb Space Telescope, researchers detected molecules in K2-18b's ...

Rogue moons drifting through space may host long-lived oceans for up to 4.3 billion years, expanding where scientists search ...

A rocky, Earth-size planet located in our Milky Way galaxy may have an atmosphere around it, according to new research, raising the possibility that it could also have liquid water on its surface and ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain ...

An ocean world that’s teeming with microbes — and who knows what other kinds of life — is currently the best explanation for some chemical signatures that the James Webb Space Telescope has spotted in ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. Earth-like ...

Astronomers’ favorite fable just got a new twist. The “Goldilocks zone” — the region of space not too close and not too far from a star where liquid water could exist on a planet’s surface — now has a ...
