NSF-NOAA GONG Maps Hidden Magnetism on the Sun’s Far Side

Sound Waves Inside The Sun Now Reveal Magnetic Secrets On Its Hidden Far Side

Los Angeles CA (SPX) Apr 25, 2026 For observers on Earth, the Sun appears as a bright, familiar disk - but what we see is only half the story. Like the Moon, one half of the Sun is permanently hidden from our direct view: the far side beyond the visible solar limb. Yet, activity brewing there can eventually turn toward Earth, sometimes unleashing solar flares and eruptions capable of disrupting human technology. A quarter

NSF-NOAA GONG Reveals Hidden Magnetic Activity on the Sun’s Far Side

BOULDER, CO — April 25, 2026 — From our vantage point on Earth, the Sun presents itself as a luminous, seemingly uniform disk, an image deeply ingrained in scientific understanding and popular imagination alike. However, what meets our eyes represents only one hemisphere—the near side—while the far side remains perpetually concealed beyond the Sun’s visible limb. This hidden side harbors solar activity that can eventually rotate into Earth’s vie…

NSF-NOAA GONG Maps Hidden Magnetism on the Sun’s Far Side

Understanding the Sun’s active regions is crucial for predicting space weather, but scientists have historically lacked continuous, detailed measurements of the Sun's hidden far side. New research by a team of scientists led by the U.S. National Science Foundation (NSF) National Solar Observatory have developed a novel approach to estimate the magnetic configuration of these hidden regions using helioseismic data (sound waves within the Sun). The

Scientists map hidden magnetic fields on the sun's far side

From Earth, we only ever see half of the sun. The other half—the far side—is always hidden from view. But what happens there still matters. Powerful activity forming on the far side can rotate toward Earth and trigger solar storms that affect satellites, communication systems and power grids. Now, scientists have developed a new way […] The post Scientists map hidden magnetic fields on the sun’s far side appeared first on Knowridge Science Repor…
