Much of the world around us cannot be seen by the naked eye — we need techniques such as scanning electron microscopy or satellite imaging. For instance, the fine detail shown here of the coiled shell of the tun (Tonna galea), a marine carnivore, was obtained using false-colour X-ray techniques. In Heaven & Earth: Unseen by the Naked Eye (Phaidon, £29.95, $49.95, 49.95 euros), David Malin has compiled a stunning collection of images, which without such techniques would be lost to us, of objects ranging in size from a tiny gold atom to galaxies billions of light years away.
