Strange life signs found on meteorites * 2
    #534319 - 03/07/11 06:25 PM (7 years, 3 months ago)

Reuters) - A NASA scientist reports detecting tiny fossilized bacteria on three meteorites, and maintains these microscopic life forms are not native to Earth.

If confirmed, this research would suggest life in the universe is widespread and life on Earth may have come from elsewhere in the solar system, riding to our planet on space rocks like comets, moons and other astral bodies.

The study, published online late Friday in The Journal of Cosmology, is considered so controversial it is accompanied by a statement from the journal's editor seeking other scientific comment, which is to be published starting on Monday.

The central claim of the study by astrobiologist Richard Hoover is that there is evidence of microfossils similar to cyanobacteria -- blue-green algae, also known as pond scum -- on the freshly fractured inner surfaces of three meteorites.

These microscopic structures had lots of carbon, a marker for Earth-type life, and almost no nitrogen, Hoover said in a telephone interview on Sunday.

Nitrogen can also be a sign of Earthly life, but the lack of it only means that whatever nitrogen was in these structures has decomposed out into a gaseous form long ago, Hoover said.

"We have known for a long time that there were very interesting biomarkers in carbonaceous meteorites and the detection of structures that are very similar ... to known terrestrial cyanobacteria is interesting in that it indicates that life is not restricted to the planet Earth," Hoover said.

Hoover, based at NASA's Marshall Space Flight Center in Alabama, has specialized in the study of microscopic lifeforms that survive extreme environments such as glaciers, permafrost and geysers.

He is not the first to claim discovery of microscopic life from other worlds.

In 1996, NASA scientists presented research indicating a 4-billion-year-old meteorite found in Antarctica carried evidence of fossilized microbial life from Mars.

The initial discovery of the so-called Mars meteorite was greeted with acclaim and the rock unveiled at a standing room-only briefing at NASA headquarters in Washington.

Since then, however, criticism has surrounded that discovery and conclusive proof has been elusive.

Hoover's research may well meet the same fate. In a statement published with the online paper, the Journal of Cosmology's editor in chief, Rudy Schild, said in a statement:

"Dr. Richard Hoover is a highly respected scientist and astrobiologist with a prestigious record of accomplishment at NASA. 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."

you know what i did in english class? I came to class stoned out of my mind every day, i chugged vodka in the back of class, i put dead fish in the ceiling tiles. i put a gallon of old milk and orange juice in the file cabinet before winter vacation. i brought snakes in a tied up sweater and let them loose during class. i didnt go to school to learn, i went because i had to. i didnt care, and i didn't fucking listen to that stupid bitch. and i still don't fucking care. i tore the pages out of her books and burned them, and threw away all the books in the class, two books per day.  :twobooks:

Was this ever confirmed or not?

Actually if you read a few of the peer-responses it seems that he was relatively on point.
