NASA and ESA Track Record-Breaking 19-Day Solar Radio Burst
For nearly three weeks, a strange radio signal appeared to circle the sun. One spacecraft would watch the signal fade from view, only for another elsewhere in the Solar System to detect it days later as the sun rotated. Instead of disappearing like most solar radio bursts, the signal kept returning. By the time it finally faded in September 2025, the burst had lasted 19 days, making it the longest Type IV solar radio burst ever recorded. The previous record lasted only about five days.
The event was tracked by several NASA missions, including Parker Solar Probe, Wind, and STEREO, as well as the joint ESA-NASA Solar Orbiter mission. The findings, published in The Astrophysical Journal Letters, trace how the sun may have sustained the radio burst for so long.
