"Since 1990, the Hubble Space Telescope has floated silently above Earth, collecting data that has revolutionized our view of the cosmos. From objects in our own solar system to galaxies and nebulae at the farthest reaches of space, Hubble's high-resolution images have captured the public's imagination and given astromoners new information about the dynamics and evolution of the universe. This calendar's twelve photographs, each accompanied by an informative description, provide a sample of the awe-inspiring celestial phenomena documented by Hubble. Important dates in space exploration history and current astronomical events are noted throughout."
