Proof of Alien Bacteria? Not so fast.
Sunday, March 6th, 2011You may well have already seen some of the numerous news reports on claims that fossilized bacteria has been found in a meteorite sample. (no, not the Martian one from 1996) It has been making the rounds in a number of press outlets. If you have not caught it, here’s an example.
Strange life signs found on meteorites-NASA scientist
WASHINGTON, March 6 (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.

Instead, he repeatedly insisted that he get a sit-down interview with Phil Plait. Phil was quite civil, and informed him that to get scheduled interview time he would need to register as press. The Amazing Meeting does not have very exclusive standards for who is given press status – bloggers and podcasters can easily get it. When he was asked for his information on this topic, he repeatedly made a scene about not wanting to reveal his background. I’m not sure how things worked out, but eventually he got a press pass and thus could get his interview. Unfortunately for him, Phil Plait decided to decline the request. After rudely interrupting Phil, who was trying to converse with others at the conference, the Little Dude from the Moon finally started yelling at Phil that he thought his answers were dishonest and he was a liar. Phil said something about how he didn’t believe he could say anything that would change the Little Dude’s mind and that if the Little Dude felt that way, he was not interested in sitting down for an interview.
