Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is ...

A possible alien planet discovered by NASA's Kepler space telescope is the most Earth-like world yet detected beyond our solar system, scientists say. With a radius that is just 1.5 times that of ...

Nasa recently confirmed that the total number of known exoplanets, alien planets orbiting stars beyond our Solar System, has reached an impressive milestone of 6,000. This reflects decades of cosmic ...

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 ...

The Penn State-led Habitable Zone Planet Finder (HPF) provides the highest precision measurements to date of infrared signals from nearby stars. Pictured: The HPF instrument during installation in its ...

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 ...

Scientists using NASA’s James Webb Space Telescope have found a unique planet in another star system that’s shaped like a lemon. The lopsided Jupiter-style planet is so bizarre that it may blur the ...

Astronomers have spotted more than 100 new potential alien planets, including one in the fourth-closest star system to the sun, a new study reports. This haul of newfound possible exoplanets, which ...

A newly discovered “super-Earth” planet could allow us to finally see alien life, researchers say. The world – named GJ 251 c and lying less than 20 light years away – is thought to be a “super Earth” ...

A recent conundrum about a star 1,500 light years away discovered by the Kepler Space Telescope has extraterrestrial enthusiasts crying "alien" as an explanation, but scientists studying the star are ...

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 ...
