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.

By constellation:



NGC 2215 (Open cluster)
Right ascension: 6h 21m Declination: -7° 18'
Constellation: Monoceros
Date/time: 2011.01.28 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 27' Magnification and filter(s): 100x
Seeing: 8/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Small, relatively compact open cluster that reminds me of some prehistoric stone axe. Consists about a dozen stars of the 11-12m range and some fainter ones. Not an easy object as its declination requires much work with a Dobsonian telescope. :) SQM reading: 20.6m/arcsec2, -9°C, high humidity.
