A frozen moon barely wider than an asteroid has revealed itself to be one of the solar system's most consequential electromagnetic actors. Scientists poring over 13 years of data from the Cassini spacecraft have found that Enceladus — through its erupting water plumes and their charged interactions with Saturn's magnetic field — generates a rippling lattice of waves stretching more than 500,000 kilometers into space. In the long human effort to understand how small things shape large systems, this discovery reminds us that scale and influence are rarely the same measure.
