Wormholes were first introduced to the public over a century ago in a book written by an Oxford mathematician. Perhaps realizing that adults might frown on the idea of multiply connected spaces, he wrote the book under a psuedonym and wrote it for children. His name was Charles Dodgson, his psedonym was Lewis Carroll, and the book was Through The Looking Glass.

NGC 6517 (Globular cluster) Right ascension: 18h 02m Declination: -8° 58' Constellation: Ophiuchus Date/time: 2009.06.18 22:00 UT Equipment: 12" f/5 Newtonian FoV: 16' Magnification and filter(s): 250x Seeing: 7/10 Transparency: 4/5 Location: Nádasdladány, Hungary Observer: Ferenc Lovró Description: A very dim, faint globular cluster that seems to be elongated in the N-S direction. Its core brightens softly, but it refuses to split up into stars even with averted vision and it also fails to respond to increasing magnifications. The object sits in the middle of some brighter stars that form a giant V-letter, pointing to the West. Hi-resolution image: [ reversed sketch | original sketch ]
