The scientific equivalent of a fine-toothed comb may soon sweep across the skies looking for Earthlike planets outside our solar system.
Dubbed the astro-comb, the technology improves on a highly successful planet-hunting technique called the radial velocity—or wobble—method, which looks for small shifts in the wavelengths of a star's light caused by the gravitational tug of an orbiting planet.

remember when astronomers not so long ago used to manually do that tedious superimposition by careful "trial and error" ? well...who gets to name the discoveries when this thing finds 'em?
