30 Years of GONG: The Enduring Legacy of the U.S. National Science Foundation National Solar Observatory Solar Monitoring Network

Sometimes the most remarkable scientific achievements aren’t just the ones that dazzle in a moment, but the ones that endure. When the Global Oscillation Network Group (GONG) began operations in 1995, it was designed to run for just three years. Funded by the U.S. National Science Foundation and operated by the NSF National Solar Observatory (NSF NSO), the goal was focused and finite: build a global network of telescopes capable of measuring vibrations on the Sun’s surface and use them to probe.
