After years of observations and painstaking analysis, an international team of astronomers using independent Earth-based instruments has discovered what they believe is a potentially habitable, ...

At a distance of 4.2 light years, Proxima b is the closest potentially habitable Earth-like planet outside our solar system. New research suggests this distant orb could be completely covered in water ...

Scientists have discovered a planet that appears to be similar to Earth circling the star closest to the sun, potentially a major step in the quest to find out if life exists elsewhere in the universe ...

It was just over 20 years ago—a blink of a cosmic eye—that astronomers found the first planets orbiting stars other than our Sun. All these new worlds were gas-shrouded giants like Jupiter or Saturn ...

WASHINGTON — After scanning the vast reaches of the cosmos for Earth-like planets where life might exist, astronomers have found one right next door. A planet that is rocky like Earth and only ...

A team of researchers may have spotted evidence for a new planet orbiting one of the closest stars to our own solar system, in the star system Alpha Centauri, The Guardian reports. It could end up ...

We've now cataloged thousands of planets that orbit distant stars. For most of them, our knowledge is limited to basic statistics: their size, mass, and orbital distance from their host star. And, due ...

Berkeley, Calif.—Astronomers say they may have detected a second planet around Proxima Centauri, our solar system’s nearest neighboring star. Announced at Breakthrough Discuss, an annual ...

Scientists from Rochester Institute of Technology have discovered a newborn massive planet closer to Earth than any other of similarly young age found to date. The baby giant planet, called 2MASS 1155 ...

The small planet orbiting Alpha Centauri B, just four light-years away, is too hot for life but may have habitable neighbors As humankind's radio and television broadcasts leak out into space and ...

European astronomers have discovered a planet with about the mass of Earth orbiting a star in the Alpha Centauri system -- the nearest to Earth. It is also the lightest exoplanet ever discovered ...
