Abstract:
'In 2012, the centennial year of the discovery of cosmic rays, Voyager 1 crossed the heliopause and began making the very first in-situ observations of the surrounding interstellar medium. Joined by Voyager 2 in 2018, these twin spacecraft continue to provide critical measurements of cosmic rays in a surprising, previously-unexplored plasma regime. This highlight talk will review the insights, discoveries, and open questions that have emerged from nearly a decade of cosmic ray observations in the very local interstellar medium, including: i) characteristics of the low-energy spectrum (down to a few MeV/nuc) and implications for propagation models, ii) the discovery of transient, anisotropic cosmic ray disturbances, and iii) cosmic rays in the context of our time-varying, global heliosphere.'
