NASA's Solar Dynamics Observatory came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that float above the sun, tethered to it by magnetic forces. via NASA http://ift.tt/2yhGPrr

Expedition 53 Flight Engineer Paolo Nespoli of the European Space Agency (ESA) photographed cloudy skies over Sudan during an International Space Station flyover on Oct. 22, 2017. Nespoli shared the image with his followers on social media on Nov. 6, writing, "#EarthFromSpace means also... Lots of clouds! How do they look from below?" via NASA http://ift.tt/2AhQv5K
