Nebulous

For a short while now I have been studying astronomy. It only recently occurred to me that I have in fact been studying it for most of my adult life. For most backyard astronomers, of which I am one, astronomy is the art and science of taking things that are unclear, and making them clearer. Nebulous is so, and so shall we seek to undo it! I can hear the preacher now, this too is vanity. - Drew
