A recently discovered "super Earth" located around 25 light-years from our planet is not as massive as previously thought, ...

Using complex climate models, researchers have pinned down the point at which life will no longer be able to survive on Earth ...

The latest discovery of nucleotides on an asteroid is making scientists rethink the story of how life got going ...

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and ...

As the sun expands over the coming billions of years, Earth will become inhospitable to any life more complex than a microbe ...

Long before oceans teemed with life, Earth endured relentless violence. Asteroids slammed into its surface again and again, ...

GJ 3378b has moved closer to the kind of world astronomers most want to find: small, rocky, temperate, and near enough for future telescopes to inspect in far greater detail. The planet circles a red ...

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal ...

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, ...

Our planet is unique for its ability to sustain abundant life. From studies of the rock record, scientists believe life had already emerged on Earth at least 3.5 billion years ago and probably much ...

Scientists search for exoplanets and signs of life in space because understanding whether life exists beyond Earth is one of the most important goals in modern science. In space exploration, ...
