Why do nasa.gov pics show up when you google

Examples: Page 5


Page 6


I mean, when clicked on they take your directly to the nasa.gov sites. Who names them that way for them to display when googling "conspiracy"?

It's the way google's Page Ranking's work.
The same thing goes with the normal search if you type in "Miserable Failure", look at the first website that comes up.
If all depends on how many people click that picture after searching for Conspiracy, whether it was on the normal search or image search on the 9929th page.
