Orb's Explained ?

I have personally photographed these strange phenomena ( Orbs ) and have often wondered about their origin. I was just reading CNN when I come across this article edition.cnn.com... when I began to wonder if there are other scientific explainations of Orbs apart from the usual " controlled by Aliens" rant.

Don't believe everything a scientist says. I believe we are really talking about two or so different things here. Using the word ORB shouldn't classify maybe different things as one.

There could be solid orbs, almost transparent orbs well, it could be many things.

Many of scientist throughout our history made a good living on theory. I don't think this scientist can say or any scientist can say for sure that this is true for all orbs.
