Our quest to find a “second Earth” has long occupied scientists and dreamers alike. The possibility of another world ...

According to a new study published in Astronomy and Astrophysics, an exoplanet known only as Wolf 1069 b may be a habitable planet. What’s even more exciting is that this exoplanet is only 31 ...

But we're yet to prove that, not in small part because of our inability to directly observe the rocky planets residing in their solar system's habitable zones. A habitable zone is a rather small ...

She said a key difference in the star/planet systems her team studied—a variation responsible for a planetary climate being habitable or not—was the rotational characteristics of the planets.

If a planet has a lot of water vapor, it might have a good chance of hosting life as well. This requirement is the basis of the habitable zone, the region around a star where the radiation onto a ...
