NASA recently recorded what NOAA Space Weather said was “likely one of the largest” solar flares ever sent out by the Sun. These blasts of high-energy radiation “can impact radio communications, power grids, navigation signals and pose a risk to spacecraft,” per NASA. A strong solar flare, also known as extreme coronal mass ejections (CME), could cause billions in damages and lengthy blackouts on Earth. This latest incident caused radio blackouts across the US, but Lancaster University highlighted “the worst-case scenario” from such a blast. The university study claimed that these solar storms could cause railway errors by switching signals from red to green. The sun’s activity is measured in 11-year cycles, with flares separated by range and strength from B class to C, M and the strongest, X. The National Oceanic and Atmospheric Administration revealed that the latest blast was the largest X-class since September 2017.
