Google is rolling out Knowledge Graph to all English language locations. Included in this rollout is Carousel - which puts a strip of image matches at the very top of the search results in response to a search that suits a list result.
I've not seen Carousel in the wild yet - but I have been looking. In Google's video they suggest [moons of saturn] as a search that should trigger the Carousel.
However, the current results for [moons of saturn] is simply incredible. Once extended (and it's not extended by default) this Knowledge Graph search doesn't just push the organic search below the fold - it pushes the organic results two and a half pages below the fold.
