This updated version of "Powers of Ten" provides a visualization of scale, beginning with a distant view of the Milky Way from a reference point 10 million light years from Earth (10^23). It moves through space at successive orders of magnitude until it reaches an oak tree in Florida. At that point, it moves from a single leaf through cells on the leaf surface, the nucleus of one leaf cell, chromatin, and DNA strands (a scale of 10 nanometers, or 10^-8). From this point, an artist has rendered illustrations of nucleotides, electron cloud surrounding the nucleus, the nucleus of one carbon atom, a single proton, and quarks (estimated at 100 attometers, or 10^-16 meters). Editor's Note: See Related Materials for a link to Nanoreisen, virtual "nano-journeys" that take the user deep inside a laptop microchip, an LED, and a carbon-based cell. It is formatted in descending powers of 10, from the scale of one meter to the femtometer size.
