Why is this nebula so complex? When a star like our Sun is dying, it will cast off its outer layers, usually into a simple overall shape. Sometimes this shape is a sphere, sometimes a double lobe, and sometimes a ring or a helix. In the case of planetary nebula NGC 5189, however, besides an overall "Z" shape (the featured image is flipped horizontally and so appears as an "S"), no such simple structure has emerged. To help find out why, the Earth-orbiting Hubble Space Telescope has observed NGC 5189 in great detail. Previous findings indicated the existence of multiple epochs of material outflow, including a recent one that created a bright but distorted torus running horizontally across image center. Hubble results appear consistent with a hypothesis that the dying star is part of a binary star system with a precessing symmetry axis. NGC 5189 spans about three light years and lies about 3,000 light years away toward the southern constellation of the Fly (Musca). via NASA

What planets are those behind that unusual rock spire? Saturn (lower left) and Jupiter.  This month, after sunset, the bright planetary duo are quite prominent toward the southeast.  Now your view of our Solar System's largest planets might not include a picturesque hoodoo in the foreground, nor the spectacular central band of our Milky Way Galaxy across the background, but should be quite eye-catching anyway.  The featured image is a composite of consecutive foreground and background exposures all taken in late May with the same camera and from the same location -- the badlands of the  Ah-Shi-Sle-Pah Wilderness in the San Juan Basin in New Mexico, USA.  The rock spire, informally dubbed 'Alien Throne', stands about 3 meters tall. Saturn and Jupiter will remain visible together after sunset for several months. via NASA
