Another amazing photo to set your mind spinning over the scale of the universe. Every object in the photo above is an entire galaxy each of which contains billions of stars! To quote the site…

The image shows a rich tapestry of 7,500 galaxies stretching back through most of the universe’s history. The closest galaxies seen in the foreground emitted their observed light about a billion years ago. The farthest galaxies, a few of the very faint red specks, are seen as they appeared more than 13 billion years ago, or roughly 650 million years after the Big Bang. This mosaic spans a slice of space that is equal to about a third of the diameter of the full Moon (10 arcminutes).
