This planetary nebula, Mz3, is being cast off by a star similar to our Sun. The 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star visible at the nebula's center, all imply Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holds that the central star's own spin and magnetic field are channeling the gas. (ESA, NASA's Hubble, JPL-CalTech)

Speeding Towards Jupiter's Pole

Picture of the day for August 27 2016 by Nasa Jupiter's north polar region is coming into view as NASA's Juno spacecraft approaches the giant planet. This view of Jupiter was taken on August 27 when Juno was 437000 miles (703000 kilometers) away. The Juno mission successfully executed its first of 36 orbital flybys of Jupiter.

Redstone-Mercury: yes, Shepard and Grissom rode that tiny thing into space. Couldn't even reach orbital speed.
