NASA Detects Bizarre Solar Radio Burst That Wouldn’t Stop
SciTechDaily • • science
Key Points:
- In August 2025, NASA scientists detected an unprecedented Type IV solar radio burst from the Sun that lasted 19 days, far exceeding the previous record of five days for such events.
- The burst originated from a massive magnetic structure known as a helmet streamer and was likely sustained by three coronal mass ejections erupting from the same region.
- Multiple spacecraft, including NASA’s STEREO, Parker Solar Probe, Wind missions, ESA’s Solar Orbiter, and others, observed the burst from different vantage points, allowing researchers to compile a comprehensive timeline.
- This long-duration solar radio burst provides new insights into solar magnetic activity and could improve space weather forecasting, which is crucial for protecting satellites, spacecraft, and space-based technology.
- The findings were published in The Astrophysical Journal Letters and introduce a novel method for pinpointing the origins of solar radio bursts using multi-spacecraft data.
