Earth-like planets in the habitable zone can easily be up to a billion times dimmer than their host star, said Nico Deshler of the University of Arizona. That vast difference in brightness is a steep ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

Warmer climates than Earth’s could accelerate life’s development, potentially increasing the number of planets with more ...

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they ...

An international team of astronomers reports the discovery of a new giant exoplanet around an M-dwarf star (GEMS). The ...

Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the ...

Webb Telescope finds crystalline water ice around star HD 181327. This discovery could reveal how icy bodies contribute to ...

“This is a transformational moment in the search for life beyond the solar system, where we have demonstrated that it is possible to detect biosignatures in potentially habitable planets with ...

The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study.

Astronomers have discovered many such planets, but their distance from Earth makes them difficult to study in detail. Mars, along with Earth and Venus, resides in or near the "habitable zone" of ...

Even though this planet lies in the “habitable zone” of the dwarf star, one must point out that the vicinity of this class of stars is not likely to be very hospitable, due to frequent flares ...

(Web Desk) - A ‘super-Earth’ exoplanet has been found outside of our solar system and it could have the right conditions to ...
