Whoa, this is amazing. This is the deepest and sharpest (and you could also say oldest) image of the universe ever taken.
And to say how cool this is, the total area of this image is a patch of sky the size of a grain of sand held at arms length, and every single dot of light in this image is a galaxy, not individual starts!
Just think about it. This single image contains trillions of stars and it's barely a fraction of the universe. Gives you some perspective.
