Unlike our Moon, they can keep water in oceans liquid for more than 4 billion years.

Alien solar systems that are home to so-called "hot Jupiters" — gas giants circling sizzlingly close to their stars — are unlikely homes for Earth-like planets, researchers say. Hot Jupiters get their ...

Beyond that, in the decades to come, we might be able to see the colours of an exoplanet’s surface, and determine if plant life might be present there. And then we can search for changes in a planet’s ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...

Astronomers have discovered 41 new alien planets in one sweep by analyzing how each world gravitationally yanks on its neighbors. The newly confirmed exoplanets were spotted by NASA's prolific Kepler ...

NASA has confirmed 6,000 exoplanets, marking a major milestone in humanity’s quest to understand other worlds. From gas giants hugging their stars to planets covered in lava or clouds of gemstones, ...

First-year students in Rochester Institute of Technology’s Science Exploration Program are reproducing a slice of life in their lab that might exist on the seven Earth-like planets recently discovered ...

New research finds that certain large exoplanets are shrinking due to internal processes, creating an abundance of rocky 'super-Earths'. When you purchase through links on our site, we may earn an ...

For the first time, scientists have directly detected molecules in a Frisbee of gas and dust swirling around an alien gas-giant planet. “I didn’t think this was possible,” says astronomer Sierra Grant ...
