An astronomer really risks his or her reputation if he or she suggests that the universe has a preferred direction. A core belief in cosmology maintains that no
point or direction in the cosmos is in any way "special."
So, B. Nodland and J.P. Ralston stirred up a hornets' nest this past spring when they published a paper that began with this paragraph:
"Polarized electromagnetic radiation propagating across the Universe has its plane of polarization rotated by the Faraday effect. We report findings of
an additional rotation, remaining after Faraday rotation is extracted, which may represent evidence for cosmological anisotropy on a vast scale." (Ref.
Most inflammatory was their claim that the plane of polarization of the radio waves rotated more along a particular direction [axis?]; specifically, along a line
connecting the constellations Aquila and Sextans. (Ref. 2)
Only a few days after the NodlandRalston paper was published, it was blasted in Science. The major complaint was that their data were old and incomplete,
since they derived mainly from observations made prior to 1980. (Ref. 3)
Indeed, a similar study using more recent measurements but fewer radiation sources seems to refute the NodlandRalston claim of a preferred direction in the
cosmos. (Ref. 4)
Nodland and Ralston disagree with the charges and the implications of the other study. It will be a while before this is all sorted out. The paradigm that
Nodland and Ralston are challenging is deeply entrenched and of great philosophical import. (There's nothing "special" in the cosmos, especially humans!)

"A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980
"An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983

"Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
