Which is NOT pseudoscience?

Ghosts
Astrology
UFOs
Astronomy

Astronomy

Explanation:

The reason why is because, ghosts aren't real unless proven otherwise but, currently there is no proof, there hasn't really been any proof of UFO's because, currently that is just a speculation, astrology is the study of stars but, saying things like if you see a circle of stars then there will be a war. (I made that up but its an example) There are no proof for those three but, astronomy is real because, it is the study of stars and planets basically what NASA does.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
