VLBA Maps Turbulent “Weather” in the Milky Way

By analyzing nearly a decade of NSF VLBA observations of the quasar TXS 2005+403, an international team led by the Center for Astrophysics | Harvard & Smithsonian (CfA) directly measured the tiny, turbulence-driven “ripples” imprinted on the quasar’s radio signal as it passes through a particularly chaotic region of the Milky Way.
