This visualization of the interior of a rotating Bose-Einstein condensate shows an array of 12 spontaneously appearing vortices. Bright regions correspond to low condensate density, and color denotes the phase of the condensate wavefunction. Experimental and theoretical developments in Bose-Einstein condensation are discussed in articles by Wolfgang Ketterle (page 30) and by Keith Burnett, Mark Edwards, and Charles Clark (page 37).
