Knowing that the study will be controversial, the journal invited members of the scientific community to analyze the results and to write critical commentaries ahead of time. Though none are online yet, those comments will be posted alongside the article, said Dr. Rudy Schild, a scientist with the Harvard-Smithsonian's Center for Astrophysics and the editor-in-chief of the Journal of Cosmology.
"Given the controversial nature of his discovery, we have invited 100 experts and have issued a general invitation to over 5,000 scientists from the scientific community to review the paper and to offer their critical analysis," Schild wrote in an editor's note along with the article. "No other paper in the history of science has undergone such a thorough vetting, and never before in the history of science has the scientific community been given the opportunity to critically analyze an important research paper before it is published, he wrote."
Dr. Seth Shostak, senior astronomer at the SETI Institute, said there is a lot of hesitancy to believe such proclamations. If true, the implications would be far-reaching throughout the fields of science and astronomy, the suggestions and possibilities stunning.
“Maybe life was seeded on earth -- it developed on comets for example, and just landed here when these things were hitting the very early Earth,” Shostak speculated. “It would suggest, well, life didn’t really begin on the Earth, it began as the solar system was forming.”
Hesitancy to believe new claims is something common and necessary to the field of science, Hoover said.
“A lot of times it takes a long time before scientists start changing their mind as to what is valid and what is not. I’m sure there will be many many scientists that will be very skeptical and that’s OK.”
Until Hoover’s research can be independently verified, Marais said, the findings should be considered “a potential signature of life.” Scientists, he said, will now take the research to the next level of scrutiny, which includes an independent confirmation of the results by another lab, before the findings can be classified “a confirmed signature of life.”
Hoover says he isn’t worried about the process and is open to any other explanations.

Scientists dismiss alien life report
A NASA researcher says he has found fossil bacteria in meteorites, but even his employer declines to stand behind that claim.

A report claiming to find remnants of alien life in meteorites has been broadly dismissed by scientists after its publication Friday in an eccentric online journal.
The report was written by Richard Hoover, an engineer at NASA's Marshall Space Flight Center in Huntsville, Ala. He had sliced open a couple of small meteorites, looked at them under a microscope and seen what he thought were the fossils of tiny bacteria called cyanobacteria.
Hoover wrote his report, concluding that life is common throughout the universe. He submitted a paper to the Journal of Astrobiology, which rejected it.
Hoover then sent his paper to the online Journal of Cosmology, which promotes the idea that life on Earth came from outer space. A report by Fox News on the paper triggered a meteor storm of publicity over the weekend, followed quickly by derision from mainstream scientists.
NASA has distanced itself from Hoover's work. In an unusual step Monday, Paul Hertz, chief scientist of NASA's science mission directorate, issued a statement saying, among other things, that "NASA cannot stand behind or support a scientific claim unless it has been peer-reviewed or thoroughly examined by other qualified experts.... NASA was unaware of the recent submission of the paper to the Journal of Cosmology or of the paper's subsequent publication."
The Journal of Cosmology is a 2-year-old publication developed by Rudy Schild of the Harvard-Smithsonian Center for Astrophysics that has unabashedly promoted the thesis that life exists throughout the universe and was brought to Earth from elsewhere. The journal has published just 13 issues and, in a news release Monday, said it would cease publication in May, "killed by thieves and crooks" at the journal Science and other subscription-based periodicals, whom it has accused of stifling its ability to distribute news.
The Journal of Cosmology claims to be peer-reviewed. In this case, the journal's editors said it had sent a copy of Hoover's article to 100 prominent scientists for critiques and would publish them as they come in. In normal scientific publishing, peer review is conducted before a paper is published to ensure accuracy.
The assessment of scientists, for the main part, has been harsh. "I'm surprised anyone is granting it any credibility at all," wrote blogger and biologist Paul Z. Myers of the University of Minnesota.
"Move along folks. There's nothing to see here," wrote Rosie Redfield, a microbiologist at the University of British Columbia, saying that it is easy to find structures in nature that appear similar to bacteria.
"This appears to be science by wishful thinking," Redfield said in a telephone interview.
Hoover has not responded to media requests for interviews.
Others said that even if the traces Hoover spotted in the meteorite should prove to be bacteria, it would be difficult to rule out contamination.
This is not the first time that researchers have claimed to find fossils in a meteorite. In 1996, a NASA researcher — this time with the agency's imprimatur — said he had found fossil bacteria in a meteorite that had been blasted off the surface of Mars. The report, which was published in the journal Science, was featured on the cover of Time magazine and was trumpeted by the White House.
Eventually, however, most scientists concluded that what researchers had seen were merely rock formations that looked like fossils.
Last year, NASA-sponsored researchers said they had discovered that certain bacteria in Mono Lake in California could incorporate arsenic into their DNA in place of phosphorus, arguing that the finding indicated the possibility of unusual life forms in space. That conclusion also was derided by other scientists.
