A New Study Reveals We Could Be Underestimating the Sun’s Magnetic Field — By Half - NSO - National Solar Observatory

We could have been seeing only half of the Sun's magnetism. A new study led by scientists at the U.S. National Science Foundation National Solar Observatory shows that NASA’s go-to solar telescope could be underestimating the Sun’s magnetic field by half. Using cutting-edge simulations, scientists traced every step from solar plasma to telescope image—and uncovered a hidden magnetic signal with major implications for space weather forecasts.
