BTW, I do have a little experience with comets. Here is a picture I took of Hale Bopp in April of 1997:
If you look closely enough, you'll see the alien spaceship in its tail, on its way to pick up the Heaven's Gate people.
(And if you read the history of Hale Bopp, they were saying the EXACT same things about aliens and Planet X and NASA coverups as they are about Elenin now.)
