On July 5, 2017, NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. This image shows a blended view of the sunspot in visible and extreme ultraviolet light, revealing bright coils arcing over the active region — particles spiraling along magnetic field lines.
NASA astronaut Randy Bresnik looks through the hatch of the International Space Station's Bigelow Expandable Aerospace Module (BEAM) on July 31, 2017. The BEAM is an experimental expandable module just over halfway into its planned two-year demonstration on the space station.
NASA astronaut Randy Bresnik photographed Super Typhoon Noru on August 1, 2017, as the International Space Station passed overhead. He shared images of the massive storm on social media, writing, "Super Typhoon #Noru, amazing the size of this weather phenomenon, you can almost sense its power from 250 miles above."
