Anniversaries: Hubble's Fifteenth

"During the 15 years NASA's Hubble Space Telescope has orbited the Earth, it has taken more than 700,000 photos of the cosmos; images that have awed, astounded and even confounded astronomers and the public. NASA released new views...of two of the most well-known objects Hubble has ever observed: the Whirlpool Galaxy spiral galaxy M51 and the Eagle Nebula."These new images are among the largest and sharpest Hubble has ever taken. They were made with Hubble's newest camera, the AdvancedCamera for Surveys. The images are so incredibly sharp, they could be enlarged to billboard size and still retain stunning details." -- from the website. <http://hubblesite.org/> <http://babyurl.com/jWoJgj>
