When Worlds Collide

Two planets in a far away solar system COLLIDED!! This article -- from, says that they were similar to Earth and Venus and that there could've been life on at least one of them. A similar situation is said to happened in our solar system. It's speculated that the moon was created by an object as big as Mars colliding with Earth. There's also a "small probability for collisions of Mercury with Earth or Venus sometime in the next billion years or more" but as the article adds, "by then, the sun will have expanded and we might be toast anyway."
