WHAT WE DON'T KNOW ABOUT COMETS (ALMOST ANYTHING!) - Dr Paul Francis
A few times every year, comets wander into our solar system, out from
the vast darkness beyond Pluto. Where do they come from? And why do
they come to visit us? We don’t know, though there are several wild
theories, some involving vast rings containing trillions of orbiting
ice-blocs, or whole families of planets hundreds of times further out
than Pluto. I’ll review these mysteries, and the enduring puzzle of
what might lurk in the vast, dark, unexplored reaches between Pluto
and the nearest stars.
