As a pre-solar cloud of material collapsed, radiation began shaping the chemical makeup of the solar system.
In another sign that there's more to the solar system than meets the eye, astronomers find two small moons orbiting a space rock.
The hypothesis would solve a longstanding mystery.
Scientists suspected they were there. Now they've spotted nearly a dozen in just a small patch of sky.
With the discovery of a new world larger than Pluto, astronomers feel the need to define the term "planet." But can they agree on anything?
