The number of known places in our galaxy theoretically hospitable to life may be significantly greater than previously thought, according to new research.
Researchers with Planet Hunters are reporting the discovery of a Jupiter-sized planet in the so-called “habitable zone” of a star similar to Earth’s sun, as well as the identification of 15 new candidate planets also orbiting within their star’s habitable zone. (more…)
New research led by Yale University scientists suggests that a rocky planet twice Earth’s size orbiting a nearby star is a diamond planet.

The paper reporting the findings has been accepted for publication in the journal Astrophysical Journal Letters. (more…)
