The Grand Power Law of turbulence in the Milky Way from in situ observations of Voyager 1 The electron density power spectrum with scales of 50m to 15au in the local interstellar medium is obtained from in situ observations of Voyager 1. By combining the in situ data with the earlier ground remote observations, we now have the turbulent spectrum extending from 50m to 100 light-years, over 16 orders of magnitude.(DOI: 10.1038/s41550-018-0650-6)
