Scientists skeptical of meteorite alien life claim

NASA and its top scientists are distancing themselves from a space agency researcher who concludes that he found alien bacterial life in meteorites that were collected many decades ago.

Richard Hoover of NASA's Marshall Space Flight Center in Huntsville, Ala., claims he found fossils that look like the remnants of bacteria in at least two meteorites. His research paper, published online Friday in the Journal of Cosmology, concludes these must have come from outer space.

But his claim has been roundly disputed by other scientists.

"There has been no one in the scientific community, certainly no one in the meteorite analysis community, that has supported these conclusions," Carl Pilcher, director of the NASA Astrobiology Institute, told the Associated Press on Monday. "The simplest explanation for Mr. Hoover's measurements is that he's measuring microbes from Earth. They're contamination."

In the paper, Hoover states that chemical analysis makes it unlikely to be contamination. Instead, he wrote they are "indigenous fossils" from outer space rather than something found on Earth.

Scientists inside and outside the space agency have criticized and even ridiculed Hoover's study, his credentials and the journal itself. They say Hoover works in solar physics and doesn't have expertise in astrobiology.

Hoover didn't return phone calls or e-mails from the AP.

Rudy Schild, a Harvard astronomer and editor-in-chief of the journal, said the study was reviewed by scientists, but he wouldn't identify them.

Schild said the idea was to garner attention and generate debate, which happened after it was first reported over the weekend by FoxNews.com.

On Monday, NASA issued a statement by Paul Hertz, chief scientist in the science division, questioning the validity of claims that have not gone through peer review. NASA said Hoover failed to advise the agency he had submitted the paper to the Journal of Cosmology after it failed to get published in a more established peer-reviewed journal.

  4. No touchdown, but fun lesson for Bucs' Adam Humphries

    Bucs

    It didn't end up being a touchdown, but one of the Bucs' biggest hustle plays in Thursday's win over Jacksonville saw receiver Adam Humphries scoop up a loose ball just before halftime, after what looked like an incompletion but was correctly ruled a Jameis Winston fumble.

    Bucs WR Adam Humphries runs to the end zone with QB Jameis Winston trailing -- his alert play wasn't a touchdown because teammates cannot advance a fumble in the final two minutes of a half.
