The event will follow the deep partial lunar eclipse of August 27-28, 2026, but the…...

2+ week, 16+ hour ago   (633+ words) A coronal mass ejection linked to a powerful solar eruption is continuing to influence Earth's space-weather outlook Saturday, Aug. 29, with NOAA forecasting periods of minor to moderate geomagnetic storm activity that could give skywatchers in far northern areas another chance…...

2+ week, 3+ day ago   (502+ words) NASA's Pandora spacecraft began its science mission Aug. 25, roughly seven months after launching into low Earth orbit, with plans to study the atmospheres of at least 20 planets outside the solar system. The small satellite will look for atmospheric features including…...

2+ week, 4+ day ago   (677+ words) A sunspot region facing Earth produced five M-class solar flares on Aug. 25, including an M6.9 event that peaked at 10:02 UTC, prompting attention from space weather forecasters as a possible CME and a separate high-speed solar wind stream approach Earth later this…...
