HUBBLE'S UNIVERSE: A Portrait of' Our Cosmos

Mars seen from the relatively close distance of 103 million kilometers; the stormy Great Red Spot above Jupiter's surface; a possible continent or sea spied through the smoggy haze that surrounds the moon Titan; a nebula with gaseous columns so dense and craggy they appear like a heavenly rock formation. These stunning images and many others, transmitted to Earth by the Hubble Space Telescope, are reprinted here in full color. Goodwin, a research astronomer at the University of Sussex in England, provides commentary, and John Gribbin, a leading popular-science writer (Fire on Earth, p. 727, etc.), provides a preface.
