NASA scientists observed a solar radio burst that lasted 19 days in August 2025, far exceeding the previous record of five days. The event was tracked using multiple spacecraft across the solar system and linked to a helmet streamer on the Sun.

The prolonged signal was identified as a Type IV radio burst, generated by energetic electrons trapped in the Sun's magnetic fields. Researchers combined data from NASA's STEREO, Parker Solar Probe, and Wind missions along with the ESA and NASA Solar Orbiter to follow the burst as the Sun rotated.

An international team has identified the brightest fast radio burst ever detected by CHIME, tracing it to the galaxy NGC 4141. Named FRB 20250316A or RBFLOAT, the burst occurred on March 16, 2025, and lasted about one-fifth of a second. Follow-up observations with the James Webb Space Telescope revealed a faint infrared signal at the location.

Space weather may have blurred SETI's search for alien signals

Researchers at the SETI Institute suggest that solar wind and plasma from stars could distort radio signals from distant intelligent life, making them harder to detect. This means past searches may have overlooked potential evidence by focusing on narrowband signals. Adjusting detection methods could improve future chances of discovery.
