'Alien Life' Story of Dubious Provenance Goes Viral
Sockatume writes "By now you have likely read about the 'alien life forms' discovered in the upper atmosphere over Yorkshire, via the mass media reprinting a press release from the University of Sheffield. Unfortunately, the paper comes from researchers with an infamous tendency to identify inanimate objects as aliens, and is published in a journal that seems to principally exist to print unlikely astrobiological claims. Phil Plait points out flaws in a number of their claims. Quoting: 'They found what appears to be a fragment of a frustrule, the hard outer casing around a diatom. It certainly does look like one. But is it? Weirdly, they apparently didn’t even check. Seriously, in the paper they describe the photo of the object and say [emphasis mine], "On one stub was discovered part of a diatom which, we assume, is clear enough for experts on diatom taxonomy to precisely identify." That implies very strongly they didn’t ask an expert in diatoms to look at their sample. That’s bizarre. If I were claiming this were an ET plant, that’s the very first thing I’d do!'" -
No, Life Has Not Been Found In a Meteorite
The Bad Astronomer writes "News is going around the web that a scientist in the UK has found life (in the form of microscopic diatoms) in a meteorite, and has even published a paper about it. However, there are a lot of reasons to strongly doubt the claim. While the diatoms appear to be real, they are certainly from Earth. The meteorite itself, on the other hand, does not appear to be real. Many of the basic scientific steps and claims made in the paper are very shaky. Also, the scientist making the claim, N. C. Wickramasinghe, has made many fringe claims like this in the past with little or no evidence (such as the flu and SARS being viruses from space). To top it off, the website that published the paper, the Journal of Cosmology, has an interesting history of publishing fringe claims unsupported by strong evidence. All in all, this claim of life in a space rock is at best highly doubtful, and in reality almost certainly not true." -
Scientists Study Trajectories of Life-Bearing Earth Meteorites
Hugh Pickens writes "About 65 million years ago, Earth was struck by an asteroid some 10 km in diameter with a mass of well over a trillion tonnes that created megatsunamis, global wildfires ignited by giant clouds of superheated ash, and the mass extinction of land-based life on Earth. Now astrobiologists have begun to study a less well known consequence: the ejection of billions of tons of life-bearing rocks and water into space that has made its way not just to other planets but other solar systems as well. Calculations by Tetsuya Hara and his colleagues at Kyoto Sangyo University in Japan show that a surprisingly large amount of life-bearing material ended up not on the Moon and Mars, as might be expected, but the Jovian moon Europa and the Saturnian moon Enceladus also received tons of life-bearing rock from earth. Even more amazingly, calculations suggest that most Earth ejecta ended up in interstellar space and some has probably already arrived at Earth-like exoplanets orbiting other stars. Hara estimates that about a thousand Earth-rocks from this event would have made the trip to Gliese 581, a red dwarf some 20 light years away that is thought to have a super-Earth orbiting at the edge of the habitable zone, taking about a million years to reach its destination. Of course, nobody knows if microbes can survive that kind of journey or even the shorter trips to Europa and Enceladus. But Hara says that if microbes can survive that kind of journey, they ought to flourish on a super-Earth in the habitable zone (PDF). 'If we consider the possibility that the fragmented ejecta (smaller than 1cm) are accreted to comets and other icy bodies, then buried fertile material could make the interstellar journey throughout the Galaxy,' writes Hara. 'Under these circumstances fragments could continue the interstellar journey and Earth origin meteorites could be transferred to Gl 581 system. If we take it as viable, we should consider the panspermia theories more seriously.'" -
Making the Case For Microscopic Life In Meteorites
An anonymous reader writes "NASA scientist Dr. Richard Hoover claims he discovered evidence of extraterritorial life in a meteorite. He published his results in the March issue of Journal of Cosmology. In front of the article there is an official statement form the editor in chief: 'We believe Dr. Hoover's careful analysis provides definitive evidence of ancient microbial life on astral bodies some of which may predate the origin of Earth and this solar system. 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 5000 scientists from the scientific community to review the paper and to offer their critical analysis.'" -
Scientist Says NASA Must Study Space Sex
Velcroman1 writes "NASA has always been tight lipped on the subject of sex in space — which makes people all the more curious. How would it work? Has anyone done it before? Can a child be conceived in zero-G? With few animal tests (and virtually no human testing), there's been next to no scientific analysis of the issue. Until now. The Journal of Cosmology has published a special issue detailing the mission to Mars, which touches all the bases. In a chapter titled Sex on Mars, Dr. Rhawn Joseph from the Brain Research Laboratory in California discusses everything from the social conditions that would push astronauts to have sex to the possibility of the first child being born on another planet. Such an infant would be the first real Martian — at least by nationality, the researcher pointed out. 'On Mars, the light's going to be different, the gravity will be different, it's a completely different atmosphere,' he said. 'So if you put an infant on Mars, they would adapt to varying degrees of the new environment. And after several generations, you'd have a new species,' he said." -

Mars Journal Issue Inspires Hundreds of One-Way Trip Volunteers
Velcroman1 writes "An interplanetary trip to Mars could take as little as 10 months, but returning would be virtually impossible — making the voyage a form of self-imposed exile from Earth unlike anything else in human history. What would inspire someone to volunteer? A special edition of the Journal of Cosmology detailed exactly how a privately-funded, one-way mission to Mars could depart as soon as 20 years from now — and it prompted more than 400 readers to volunteer as colonists. 'I've had a deep desire to explore the universe ever since I was a child and understood what a rocket was,' said Peter Greaves, the father of three, and a jack-of-all-trades who started his own motorcycle dispatch company and fixes computers and engines on the side. 'I envision life on Mars to be stunning, frightening, lonely, quite cramped and busy,' he said. Given the difficulties of the mission, Lana Tao, the editor of the Journal, said she was surprised by the response. 'At first we thought the e-mails were a joke... then we realized they were completely serious.'" Of course, they'd have to compete with the thousands of you who said you'd go. -
'Colonizing the Red Planet,' a How-To Guide
Velcroman1 writes "A manned mission to Mars would be the greatest adventure in the history of the human race. And one man knows how to make it a reality. In fact, he just wrote the book on it — literally. Joel Levine, senior research scientist with NASA's Langley Research Center and co-chair of NASA's Human Exploration of Mars Science Analysis Group, just published 'The Human Mission to Mars: Colonizing the Red Planet.' The book reads like a who's who of Mars mission science, featuring senators, astronauts, astrophysicists, geologists and more on getting to Mars, studying its atmosphere and climate, the psychological and medical effects on the crew and other details. The most interesting bit: Levine presents is a solution for funding the trip, something unprecedented for NASA: advertising. 'The suggestion is marketing to different corporations and professional sports leagues for advertising, which is something NASA never does.'"
