This visualisation of the 3-D structure of the Pillars of Creation is based on new observations of the object using the MUSE instrument on ESO's Very Large Telescope in Chile. The pillars actually consist of several distinct pieces on either side of the star cluster NGC 6611. In this illustration, the relative distance between the pillars along the line of sight is not to scale. ESO/M. Kornmesser hide caption

A Russian launch vehicle carrying the Progress M-27M cargo ship lifts off from the Baikonur cosmodrome in Kazakhstan on Tuesday. Fears mounted Wednesday that the unmanned cargo capsule was lost and may plunge back to Earth as ground control failed to gain control of the orbiting ship for a second day in a row.

This artist rendering shows Kepler-11, a sun-like star around which six planets orbit. A planet-hunting telescope is finding whole new worlds of possibilities in the search for alien life, including more than 50 potential planets that initially appear to be in habitable zones. The agency's chief scientist said Tuesday there will be "strong indications" of alien life within a decade. NASA/AP hide caption
