Astronaut Suni Williams checks out the Astrobee robotic free-flyer outfitted with tentacle-like arms containing gecko-like adhesive pads to demonstrate satellite capture techniques. The Progress 90 cargo craft is orbiting Earth and on its way to resupply the International Space Station after its launch Thursday morning. In the meantime, the Expedition 72 crew continued exploring space [...]

NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging [...]
