摘要

Less than a century ago, astrono- mers were still not convinced that there existed galaxies beyond our own. The known universe consisted of our Milky Way; all of what are now known to be external galaxies were thought to be clouds of gas or clusters of stars within it. Armed with mod- ern knowledge, today's observer sees these faint, nebulous smudges very differently than preceding genera- tions, with an added sense of wonder and awe. Isolated galaxies become objects of unimaginable dimen- sion, and groups of galaxies suggest impossibly vast structures. We are privileged to perceive these groups for what they actually are, which makes observing them great fun.
