Earth `air` found on Moon

The Moon's soil is impregnated with nitrogen that came from Earth. This was stated by Japanese scientists in the weekly British science journal Nature. The researchers, giving a new interpretative spin on analysis of lunar soil brought home by the Apollo missions, believe that the nitrogen escaped from Earth's upper …

Sun may have captured asteroids from afar

The Sun may have captured thousands or even millions of asteroids from another planetary system during an encounter more than four billion years ago, astronomers reported. Such an interstellar ballet would explain many mysteries of the outer solar system, including the strange behavior of the recently discovered Sedna, the system's …
