Astronomers present a concept for the next NASA flagship mission

Canadian astronomers determine Earth's fingerprint in hopes of finding habitable planets beyond the Solar System

There may be more habitable planets in the universe than we previously thought, according to Penn State geoscientists

In a recent study, calculated water loss rates as well as geophysical water release rates favor the idea that the outermost, more massive planets retain their water

All of these seven planets could have liquid water—key to life as we know it—under the right atmospheric conditions, but the chances are highest with the three in the habitable zone

For the first half of 2016, telescopes around the world monitored Proxima Centauri in a coordinated effort called the Pale Red Dot campaign

Announcement more than doubles the number of confirmed planets from Kepler

Simulations dispute dogma: rocky planets may orbit double stars.
