Arctowski Medal

The Arctowski Medal is presented every two years to recognize outstanding contributions to the study of solar physics and solar terrestrial relationships. The Medal is presented with an award of $100,000, plus $100,000 to support research in solar physics and solar terrestrial relationships at an institution of the recipient’s choice. The Arctowski Medal was established in 1958 by the bequest of Jane Arctowska in honor of her husband, Henryk Arctowski.

Stuart D. Bale, University of California, Berkeley, will receive the 2025 Arctowski Medal.

Bale has revolutionized our understanding of the energization of and heat transport in the solar wind.

Bale’s seminal work includes the development and operation of space-borne experiments to study the plasma processes active in astrophysical, heliospheric, and magnetospheric systems. His work includes leading the development of novel spacecraft instrumentation used on the NASA Parker Solar Probe mission, which is advancing our understanding of the generation of the solar wind.

Bale’s research has had a significant impact on a broad range of plasma physics phenomena, including electromagnetic waves and instabilities, collisionless magnetic reconnection and shocks, electron heat conduction, and plasma turbulence.

Bale will be honored in a ceremony on Sunday, April 27 during the National Academy of Sciences’ 162nd annual meeting. The ceremony will be livestreamed.
