The distances to other stars are depressingly enormous. Sure, it’s incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime.

Fortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All we’ve got to do… is catch them.
