By the frequency of radio waves from a cloud of solar gas, scientists directly measured its magnetic field. It turns out that the invisible force is hidden in tangled clumps, not evenly smeared across the cloud.

Using the OVRO–LWA array, astronomers conducted an unprecedented survey in the 50–86 MHz band with 10 Hz resolution. The 30-second exposure produced over three million images, setting strict limits on the power of hypothetical transmitters around nearby stars. No extraterrestrial signal was detected
