It's easy to feel small when pondering the size of the universe and the smallness of Earth in comparison. Imgur user ScienceLlama has taken this existential crisis to the next level with this collection of itty-bitty universe photos.

To create these miniaturized space scenes, like the one above depicting the Horsehead Nebula, a faux tilt-shift effect was applied to the original source images in Photoshop.

By blurring certain areas, the images take on a rudimentary illusion of depth, as if the subjects are suspended in a small diorama box.
