Imagine stepping onto a distant exoplanet, where vast alien oceans stretch beyond the horizon. Based on data from missions ...

The new planet - named Kepler-22b - has key aspects it shares with Earth. It circles a star that could be the twin of our sun and at just about the same distance. The planet's year of 290 days is ...

A planet some 600 light-years away, Kepler-22b circles its star squarely in a "habitable zone" — the orbital distance where a world's surface temperature would neither boil nor freeze water ...

Kepler-22b is an alien planet that's a bit larger than Earth, ... James Webb Space Telescope James Webb Space Telescope finds water in the air of exotic 'sub-Neptune' exoplanet.

Planet Kepler-22b might be right temperature for liquid water. Dec. 6, 2011 — -- NASA's Kepler space telescope has found a new planet-- the most Earth-like yet -- circling a yellow star ...

So far the Kepler telescope has spotted 2,326 candidate planets outside our solar system with 139 of them potentially habitable ones. Even though the confirmed Kepler-22b is a bit big, it is still ...

Of the 54 candidate planets in the “habitable” zone, where liquid water could exist, Kepler-22b is the first to be confirmed. This milestone will be published in The Astrophysical Journal.

Scientists are still do not know if the planet is rocky, like earth, or if it is more like Neptune, which is mostly water and gas. If Kepler 22b does turn out to be a small defrosted Neptune, ...

It’s a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might ...
