This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc. Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the ...

— -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a surface ...

How common are Earth-like planets in the universe? When I started working on supernova explosions, I never imagined that my ...

One of the most promising Earth-sized exoplanets may be far more barren than its early billing suggested, with new analyses pointing to a rocky world stripped of the protective gases that make a ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding star.

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

A rocky planet similar to Earth may be orbiting one of our nearest stellar neighbors and could be detected using existing techniques, according to a new study led by astronomers at the University of ...
