We may find that Io isn't the only place with a distinctly sulfurous odor. I'm picturing a planet (codename: Cassavetes)where sulfur doesn't only eject from volcanoes, but also lies in deep, molten oceans and sulfur vapor forms vast weather systems.
Cassavetes is parked in a tidally-locked orbit around a nearby star and lies so close to its neighbor that there is plenty of heat to disperse atmospherically to its unlit side and keep the weather engine operating.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
