On Thursday (April 17), NASA announced the historic discovery of Kepler-186f, an Earth-size alien planet 490 light-years from our own world that is located inside the habitable zone of its star. See Space.com's complete coverage of the Kepler-186f find.
18 April 2014, 06:01 AM ET
The discovery of Kepler-186f still falls short of the ultimate prize in exoplanet science: a true "alien Earth." But the first such world may lurk in the data already gathered by NASA's Kepler space telescope, just waiting to be pulled out.

A team of researchers detected a pair of faraway objects that could be a free-floating Jupiter-like gas giant and its moon or a small star hosting a planet about 18 times more massive than Earth. The duo's identity will likely never be known.

This is not the first time that people have seen more in Curiosity's images than is actually there. In September 2012, for example, the rover photographed a landscape that appeared to contain a rodent crouching between two rocks.

Though UFO enthusiasts may beg to differ, mission team members say that a bright flash of light visible in two images taken by the Curiosity rover on April 2 and April 3 almost certainly has a perfectly ordinary explanation.

Saturn's moon Enceladus and the Jupiter satellite Europa both harbor subsurface seas and should be studied much more closer in the future, researchers say.
03 April 2014, 02:01 PM ET
Enceladus' ocean is about 6 miles deep and lies beneath a shell of ice 19 to 25 miles thick. Further, it's in direct contact with a rocky seafloor, theoretically making possible all kinds of complex chemical reactions.

On its Asteroid Redirect Mission, NASA hopes to 'encapsulate' an asteroid using a robot ship – and also remove a boulder – before bringing the mass in range of astronauts to perform some, yet unexplained, tasks.
27 March 2014, 11:55 AM ET
NASA's Asteroid Redirect Mission, to be performed by robots, may attempt to lift a piece of loose rubble from a massive Near Earth Asteroid and return it for analysis. Here is one way this might be done.
