As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star.
In a new study, physicists led by the University of Iowa report the first definitive measurements of the sun s electric field, and how the electric field interacts with the solar wind, the fast-flowing current of charged particles that can affect activities on Earth, from satellites to telecommunications.
