Cientistas da NASA observaram uma explosão de rádio solar que durou 19 dias em agosto de 2025, superando em muito o recorde anterior de cinco dias. O evento foi rastreado usando múltiplas naves espaciais em todo o sistema solar e associado a uma estrutura conhecida como 'helmet streamer' no Sol.

O sinal prolongado foi identificado como uma explosão de rádio Tipo IV, gerada por elétrons energéticos presos nos campos magnéticos do Sol. Os pesquisadores combinaram dados das missões STEREO, Parker Solar Probe e Wind da NASA, juntamente com a Solar Orbiter da ESA e da NASA, para acompanhar a explosão à medida que o Sol rotacionava.

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.
