LONDON (AP) - Astronomers have found possible chemical signs of life on a distant planet outside our solar system, though they caution more work is needed to confirm their findings. The research, led ...

A comet traveling outside the solar system and heading toward the Earth is much larger than scientists first believed, a scientist has detailed in a new report. Avi Loeb claims the comet could even be ...

Aliens are visiting our solar system. Not little green men, sadly, but natural alien objects—cosmic bodies such as comets and asteroids born elsewhere in the galaxy that zip by the sun as they drift ...
