Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems across the planet. When these particles hit Earth's atmosphere, they create a radioactive form of carbon that trees absorb and store in their wood.
