SEATTLE —NASA has discovered the smallest planet ever seen beyond our solar system — a rocky world just 1.4 times larger than Earth — using its planet-hunting Kepler space telescope. The planet, ...

A trillion is a huge number — when you're talking dollars or euros. But a trillion miles is not so much in the cosmic scheme of things. Astronomers say they've now found a planet that orbits two suns ...

Just two weeks after the confirmation of a planet that's within the habitable zone of a distant star, the Kepler team is back with the discovery of two Earth-sized planets orbiting in what is now a ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...
