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)

I love this simple way of using brads and paper to teach kiddo how the earth rotates and orbits the sun, and how the moon does, too.

Jupiter and moons - great Hubble image. Makes me think of the Ulubis system in Iain M Banks' The Algebraist.
