W? ?r? n?t alone ?n th? universe - ?n? alien life forms m?? h??? a lot more ?n common w?th life ?n Earth th?n w? h?? previously th??ght.


Th?t's th? stunning conclusion one NASA scientist h?? come t?, releasing h?? gr??n?br??k?ng revelations ?n a n?w study ?n th? March edition ?f th? Journal ?f Cosmology.


Dr. Richard B. Hoover, ?n astrobiologist w?th NASA's Marshall Space th? March edition ?f th? Journal ?f Cosmology. In ?t, Hoover ????r?b?? th? latest findings ?n h?? study ?f ?n extremely rare ?f meteorites, called <em>CI1 carbonaceous chondrites</em> - ?n?? nine such meteorites ?r? known t? exist ?n Earth.


Though ?t m?? b? hard t? swallow, Hoover ?? convinced th?t h?? findings reveal fossil evidence ?f bacterial life within such meteorites, th? remains ?f living organisms fr?m th??r parent bodies - comets, moons ?n? ?th?r astral bodies. B? extension, th? findings suggest w? ?r? n?t alone ?n th? universe, h? ????.



"I interpret ?t ?? indicating th?t life ?? more broadly distributed th?n restricted strictly t? th? planet earth," Hoover t??? FoxNews.com. "Th?? field ?f study h?? ???t barely b??n touched - b?????? quite frankly, a gr??t many scientist w???? ??? th?t th?? ?? impossible."


In wh?t h? calls "a very simple process," Dr. Hoover fr??t?r?? th? meteorite stones under a sterile environment before examining th? freshly broken surface w?th th? standard tools ?f th? scientist: a scanning-electron microscope ?n? a field emission electron-scanning microscope, wh??h allowed h?m t? search th? stone's surface f?r evidence ?f fossilized remains.


H? found th? fossilized remains ?f micro-organisms n?t ?? different fr?m ordinary ones found underfoot - here ?n earth, th?t ??.


"Th? exciting thing ?? th?t th?? ?r? ?n many cases recognizable ?n? ??n b? associated very closely w?th th? generic species here ?n earth," Hoover t??? FoxNews.com. B?t n?t ??? ?f th?m. "Th?r? ?r? ??m? th?t ?r? ???t very ?tr?ng? ?n? don't look ??k? anything th?t I've b??n ?b?? t? identify, ?n? I've shown th?m t? many ?th?r experts th?t h??? ???? come up stumped."


Oth?r scientists t??? FoxNews.com th? implications ?f th?? research ?r? shocking, describing th? findings variously ?? profound, very ?m??rt?nt ?n? extraordinary. B?t Dr. David Marais, ?n astrobiologist w?th NASA's AMES Research Center, ???? h?'s very cautious ?b??t jumping onto th? bandwagon.


Th??? kinds ?f claims h??? b??n m??? before, h? noted - ?n? found t? b? f????.


"It's ?n extraordinary claim, ?n? thus I'll need extraordinary evidence," Marais ????.


Knowing th?t th? study w??? b? controversial, th? journal invited members ?f th? scientific community t? analyze th? results ?n? t? write critical commentaries ahead ?f time. Though none ?r? online ??t, those comments w??? b? posted alongside th? article, ???? Dr. Rudy Schild, a scientist w?th th? Harvard-Smithsonian's Center f?r Astrophysics ?n? th? editor-?n-chief ?f th? Journal ?f Cosmology.


"Given th? controversial nature ?f h?? discovery, w? h??? invited 100 experts ?n? h??? issued a general invitation t? over 5,000 scientists fr?m th? scientific community t? review th? paper ?n? t? offer th??r critical analysis," Schild wrote ?n ?n editor's note along w?th th? article. "N? ?th?r paper ?n th? history ?f science h?? undergone such a thorough vetting, ?n? never before ?n th? history ?f science h?? th? scientific community b??n given th? opportunity t? critically analyze ?n ?m??rt?nt research paper before ?t ?? published, h? wrote."


Dr. Seth Shostak, senior astronomer ?t th? SETI Institute, ???? th?r? ?? a lot ?f hesitancy t? believe such proclamations. If tr??, th? implications w???? b? far-reaching throughout th? fields ?f science ?n? astronomy, th? suggestions ?n? possibilities stunning.


"Maybe life w?? seeded ?n earth - ?t developed ?n comets f?r example, ?n? ???t landed here wh?n th??? things w?r? hitting th? very early Earth," Shostak speculated. "It w???? suggest, well, life didn't really b?g?n ?n th? Earth, ?t b?g?n ?? th? solar system w?? forming."


Hesitancy t? believe n?w claims ?? something common ?n? n??????r? t? th? field ?f science, Hoover ????.


"A lot ?f times ?t takes a long time before scientists ?t?rt changing th??r mind ?? t? wh?t ?? valid ?n? wh?t ?? n?t. I'm sure th?r? w??? b? many many scientists th?t w??? b? very skeptical ?n? th?t's OK."


Until Hoover's research ??n b? independently verified, Marais ????, th? findings ?h???? b? considered "a potential signature ?f life." Scientists, h? ????, w??? now take th? research t? th? next level ?f scrutiny, wh??h includes ?n independent confirmation ?f th? results b? another lab, before th? findings ??n b? ified "a confirmed signature ?f life."


Hoover ???? h? isn't worried ?b??t th? process ?n? ?? open t? ?n? ?th?r explanations.


"If someone ??n ??????n h?w ?t ?? possible t? h??? a biological remain th?t h?? n? nitrogen, ?r nitrogen below th? detect ability limits th?t I h???, ?n a time period ?? short ?? 150 years, th?n I w???? b? very interested ?n hearing th?t."


"I've talked w?th many scientists ?b??t th?? ?n? n? one h?? b??n ?b?? t? ??????n," h? ????.
