Parker Solar Probe maps shifting, spiky boundary where the solar wind originates

Parker Solar Probe has mapped a shifting, spiky boundary that marks where the solar wind is born, and its latest orbits show the spacecraft dives deeper into that region on each pass. The in situ measurements define fine-scale structure of the solar wind source region.

Scientists detect low‑frequency radio signature that precedes auroral substorms University of Southampton researchers report a distinct pattern of low‑frequency radio emissions that surges above auroral displays immediately before magnetospheric substorms erupt. The measurable precursor offers a new early‑warning signal for substorm onset that could inform preparations for space‑weather impacts on satellites, HF links and polar operations.
