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 ...

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” ...

The race to compile a sort of catalogue of the planets orbiting distant Suns is intensifying, with the upcoming Nancy Grace Roman Space Telescope, for instance, set to spot tens of thousands of such ...

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 ...
