NASA's Kepler mission has discovered four new planets that are less than twice the size of Earth and which orbit in their star's habitable zone.

Hubble solves a galaxy puzzle in the constellation of Centaurus

The Universe often fools our eyes, offering the false impression that celestial objects are located at the same distance from Earth. 

Vesta's black patches reveal carbon-rich asteroid impacts

New data from NASA's Dawn mission bears out the theory that the dark color of the protoplanet Vesta is caused by the impact of carbon-rich asteroids.
