This image provided by NASA July 1, 2008 shows a delicate ribbon of gas floats eerily in our galaxy. This image taken by NASA's Hubble Space Telescope is a very thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago. The supernova was probably the brightest star ever seen by humans, and surpassed Venus as the brightest object in the night time sky, only to be surpassed by the moon. It was visible even during the day for weeks, and remained visible to the naked eye for at least two and a half years before fading away. This image is a composite of hydrogen-light observations taken with Hubble's Advanced Camera for Surveys in February 2006 and Wide Field Planetary Camera 2 observations in blue, yellow-green, and near-infrared light taken in April 2008. The supernova remnant, visible only in the hydrogen-light filter was assigned a red hue in the Heritage color image.(AP Photo/NASA)
