About 500 light-years away in the constellation Cygnus lives a star, which, though smaller and redder than the sun, has a planet that may look awfully familiar.
Earth's place in the solar system is just right. It's not too hot, like Venus, and it's not too cold, like Mars, and this 'Goldilocks zone' of habitability around other stars like the sun just might be bigger than thought.
Carbon-rich planetary systems are likely bone dry, meaning 'diamond planets' probably aren't life's best friend. Continue reading →
The first detection of a massive exoplanet orbiting within a galactic bulge star's habitable zone has been discovered, leading to the hypothesis that there may be life-giving exomoons in tow. Continue reading →
As sun-like stars age, they will force the habitable zone outward, cooking previously life-giving orbits, like Earth's -- ancient red dwarf stars, however, remain stable for much longer, perhaps nurturing vastly more intelligent life. Continue reading →
Massive exoplanets inside stellar habitable zones would likely be unsuitable for life as we know it -- but what about the exomoons that are likely in tow? Continue reading →
Three potentially habitable worlds have been discovered orbiting Gliese 667C, a star only 22 light-years from Earth, tripling the potential for life evolving there. Continue reading →
According to Kepler data, the nearest 'Earth-like' exoplanet may be within 13 light-years from Earth.
