IN SPACE - MAY 4: In this handout image provided by NASA, a colourful cloud of gas and dust, a nebula named Knockout 4-55 (or K 4-55), is photographed by the Hubble Space Telescope on May 4, 2009 in Space. The nebula has an eye that appears to be looking right back at Hubble. It is the penultimate images the camera will take before NASA plans to send the shuttle Atlantis into space to make upgrades and repairs to Hubble, when astronauts will replace the telescope's camera with the Wide Field Camera 3.
