Astrophycists, and more recently sci-fi nerds, have long assumed planetary orbits around three or more stars would be fundamentally unstable due to the nature of the three-body problem. That's been thrown out with the discovery of the GW Orionis system, which has planets in orbit around all three of its stars, suggesting such a configuration is not only possible, but relatively common.

First 3D-printed metal part on the International Space Station
In August, a 'technology demonstrator' built by the European Space Agency and Airbus printed a metal part in microgravity conditions. This is an important milestone: long-term space missions aren't possible unless humans figure out a way to create spare parts and construction components and print tools on demand.
