Worlds Without End PB Framed Black-Blue 24x18J
As of 3-22-13, 861 planets outside our solar system (exoplanets) have been identified--in less than a decade. In the Milky Way Galaxy alone, there may be 100-400 billion exoplanets. Astronomers report that "at least 17 billion" Earth-sized exoplanets are present in the Milky Way Galaxy. While not all of these may be located in hospitable, life-promoting orbits around their parent star, the so-called "Goldilocks Zone," it is not unreasonable to expect that many millions of planets in our galaxy will support life. http://en.wikipedia.org/wiki/Extrasolar_planet.
I find this an exciting, but mind-boggling possibility: a stylized depiction of this possibility is shown above. An endless number of exoplanets. This fractal is comprised of sphere and diamond fractal patterns and nested spheres. Viewing at the original size permits a better appreciation of this fractal pattern at various sizes.
