Science & Engineering

Scientists found a "switch-off" point in the solar cycle where extreme space weather suddenly stops, and the sunspot count at that moment can predict the next cycle's strength seven years early. Solar Cycle 26 looks moderate, with roughly 100–120 sunspots expected at peak activity.
