And what do the astronomers postulate causes the sunlight initiated "puffs of dust," sunlight allergic Magic Dragons???

Simple.... comets are alive; composed of billions of tiny creatures that lay dormant until warmed by the suns rays. Then they awaken and begin to eat each other. Now the only question is, "are these puffs burps or farts".

Comets should be placed on the endangered species list NOW. NASA should be forbidden to continue murdering these helpless creatures. And if a collection of these wonderful creatures want to visit our planet one day, no attempt should be made to stop them. Fluff has a right to live too!

Now the only question is, "are these puffs burps or farts".
According to Aristotle ("Problemata", book 33, problem 9, IIRC), burps and farts are the same thing, but proceeding through different outlets.
