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 ...

In a secluded corner of the Lynx constellation, just 18 light-years from our planet, astronomers have found a stunning jewel—a planet around a tiny red dwarf star that may have the right conditions to ...

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 ...

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 ...

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 ...

An international team, including researchers from Penn State, has unveiled the discovery of a potentially habitable "super-Earth" less than 20 light-years from our solar system, marking a significant ...

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” ...

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 ...

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 ...

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 ...

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 ...
