NASAの科学者は2025年8月に19日間続く太陽電波バーストを観測し、従来の記録である5日間を大幅に更新しました。この現象は太陽系内の複数の探査機によって追跡され、太陽のヘルメットストリーマーに関連付けられました。
この長期間の信号は、太陽の磁場に捉えられた高エネルギー電子によって生成されるタイプIV電波バーストであると特定されました。研究者らは、NASAのSTEREO、パーカー・ソーラー・プローブ、Wind探査機のデータに加え、ESAとNASAのソーラー・オービターのデータを統合し、太陽の自転に合わせてこのバーストを追跡しました。
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.

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.
NASA’s Psyche spacecraft flew past Mars on May 15, capturing detailed images of the planet’s surface. The close encounter provided a gravity boost to speed the mission toward its main target.

Nasa has released images captured by the Psyche spacecraft during its recent flyby of Mars. The photos were taken as the probe used the planet's gravity to adjust its trajectory toward the asteroid 16 Psyche.
Debris from a Chinese Chang Zheng 4B rocket created a luminous trail over Argentine Patagonia at 0:41 a.m. on Saturday, April 4. Hundreds of witnesses in cities like Bariloche, General Roca, and Viedma recorded the event on their phones. Specialists confirmed it as a planned atmospheric reentry with no damage.
