Hoover "Cyanobacteria Fossils" Article

Post by Christopher K. » March 5th, 2011, 5:52 pm

Simply astounding. Richard Hoover of the Marshall Space Flight Center, just a few short hours ago, published a paper with the Journal of Cosmology. The first sentence of the paper's synopsis reads "Dr. Hoover has discovered evidence of microfossils similar to cyanobacteria in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites." It's that blunt.

The earliest CI1 carbonaceous meteorite found was a six-kilogram specimen in 1806 in France; that is the Alais. The 14-kilogram Orgueil was discovered in 1864, also in France. The 705-gram Ivuna was discovered in 1938 in Tanzania.

A statement from Rudy Schild of Harvard-Smithsonian reads in part "No other paper in the history of science has undergone such a thorough analysis...." I'm not quite sure how that fact could be verified, but of course Schild is attempting to get across the point that the paper wasn't published because of who the author is or the sensational subject matter.

For obvious reasons a number of Hoover's peers are being cautious--after all, we've heard variations of this claim before. From Monday to Thursday the journal will accept commentaries from other scientists to be published alongside the Hoover paper.

Apparently, Hoover has been suspecting the presence of cyanobacteria in the Orgueil piece for a while. Take a look at...

I'm asking Wally Pursell to read this article and give his input.

The new paper is here...

We shall see. I indeed hope he is right, but as you have stated, NASA has been down this road before.

A Seth Borenstein article for the Associated Press dated 7 March says that scientists "immediately found pitfalls" in the Hoover article.

Carl Pilcher, the director of NASA's Astrobiology Institute, is quoted as saying, "There has been no one in the scientific community, certainly no one in the meteorite analysis community, that has supported these conclusions." In fact, a brief four-sentence write-up entitled "Scientists Skeptical of Meteorite Alien Life Claim" is all that's posted at that site...

Clara Moscowitz says Seth Shostak is calling the paper "an extensive and thorough review" which does not "amount to convincing evidence".

Another name for cyanobacteria is blue-green algae.

There are two dozen responses to this journal concerning the Hoover article. One is a very brief statement from none other than Harrison Schmidt, who says "I only wonder why many do not seem to want life to have originated independently on Earth?"

Another responder is Tulane's Frank Tipler, who states "The very fact that cyanobacteria are so resistant to radiation is evidence that they evolved in an environment where the radiation level was much higher than on Earth today, or even the Earth of 3.9 billion years ago, the time when the Earth became a habitable planet. The universe of 11 billion years ago would have been such an environment, as star formation and death would be much more rapid then than now." However, Tipler also states "caution is called for".

Strangely, some others who posted their commentaries do not seem to be in the fields one would think. One is in a school of psychology, another in a department of neuropsychiatry.
