The Sun is not known for being quiet! It blasts out energy equivalent to 100 billion nuclear bombs every single second, routinely hurls billion tonne clouds of magnetised plasma into space, and occasionally treats us to auroras visible as far south as my home in Norfolk UK. But even by its own extraordinary standards, something that began on an unremarkable day in August 2025 turned out to be genuinely remarkable and it took a small fleet of spacecraft spread across the inner solar system to piece together what had actually happened. It started with a Type IV radio burst. These are bursts of radio waves produced when electrons get trapped inside the Sun's magnetic fields, swirling around and releasing energy as they go. They happen reasonably regularly, typically lasting a few hours to a couple of days, and while the radio waves themselves are harmless, the magnetic environments that produce them are not.…
