Astronomers can’t stop debating about the definition of a planet (see: Pluto). But one thing is for sure — there are a lot of objects that skirt the line between two types of cosmic bodies.

(Inside Science) -- Shields made of a material so light it is sometimes called "frozen smoke" could help make areas on Mars livable, a new study suggests.
Currently, the surface of Mars is too cold for water to stay liquid, often thought of as a key prerequisite for life as we know it. Moreover, its atmosphere is too thin to shield against hostile ultraviolet radiation, which is dangerous to life.
Scientists have suggested a number of s ...read more

Two pieces of animal bones with ochre engraving, found in central China, are the latest evidence that members of the human family used the material to express abstract ideas much earlier than once believed — and much further from Africa.

Tropical Storm Barry is now expected to make landfall as a hurricane.
As I'm writing this Thursday afternoon, July 12, Barry is churning slowly over the northern Gulf of Mexico, strengthening as it tarries over warm water. As it nea ...read more
