A strange solar radio burst lasted for an incredible 19 days, setting a new record. Scientists used data from multiple spacecraft to understand this unusual event.

A team of NASA scientists discovered something amazing in August 2025 when they detected a solar radio burst coming from the Sun. At first, it seemed like just another normal solar radio burst that would fade away within hours or days. But this one was different - it lasted for an astonishing 19 days! This is much longer than any previously recorded solar radio burst, which usually only lasts for a few days at most.

The scientists who studied this event were from NASA and the European Space Agency (ESA). They used data from several spacecraft to understand what happened. These spacecraft included NASA's STEREO, Parker Solar Probe, Wind, and Solar Orbiter missions.

The team found that the solar radio burst was caused by a massive magnetic structure in the Sun's atmosphere called a helmet streamer. This structure is so powerful that it can trigger coronal mass ejections (CMEs), which release clouds of charged particles and magnetic energy into space.

The scientists believe that three CMEs may have helped sustain the solar radio burst for such a long time. They think that these CMEs reorganized the large-scale trap and enabled continued injection from the low corona, maintaining the continuum.

This discovery is important because it can help researchers better recognize long-duration solar radio bursts in the future. By improving their understanding of these events, scientists may be able to strengthen space weather forecasting, helping protect satellites and spacecraft from dangerous solar activity.

Why It Matters
