A NASA astrobiologist claims to have found proof of existence of life outside Earth after finding fossil evidence of bacteria in a rare class of meteorites, published the Journal of Cosmology.
Dr. Richard B. Hoover, Marshall Space Center of the U.S. space agency (NASA), said he interpreted this finding as "a sign that life is more widely distributed and can not be restricted to the Earth."
In comments reported by FoxNews Channel, Hoover said, "This is a barely explored field of study because, frankly, many great scientists would say it's impossible."
NASA scientist drew these conclusions after studying more than a decade of extremely rare type of meteorites, the CI1, in remote areas like Antarctica, Siberia and Alaska, of which there are only nine in the Earth.
Hoover's article explains the findings of fossil evidence of bacteria similar to those known on Earth, but also traces of unknown microorganisms in these meteorites.
"The exciting thing is" that in many cases are recognizable and can be related to generic species already known, but some are really strange and not look like anything that can identify, "he said.
Hoover said that these rare specimens they have been taught to other experts and "also have been puzzled."
In anticipation of the controversy that may generate this discovery, Dr. Rudy Schild of the Harvard-Smithsonian Center for Astrophysics and editor of the Journal of Cosmology, invited members of the scientific community to comment on the article by Hoover.
"Given the controversial nature of discovery, we invited 100 experts and launched an additional invitation to more than 5 thousand scientists to review the article and offer their critical analysis," wrote Schild on the website of the Journal of cosmology.
Schild said that the intention of the magazine is adding to the Hoover article comments submitted by other scientists, both pro and con.
According to the Journal of Cosmology, "the careful analysis of Dr. Hoover provide definitive evidence of ancient microbial life in astral bodies, some of which may predate the origin of the Earth and solar system."
Hoover was aware of the controversy and skepticism that can generate a discovery of this magnitude.
"Sometimes it takes a long time before scientists change their way of thinking about what is true and what is not. I'm sure there will be many scientists who were skeptical, "he added.
Glory loss confirmed
NASA confirmed on Friday the loss of its satellite Glory after the failed launch of the Taurus rocket from the Vandenberg base LX the U.S. Air Force in California.
The rocket blasted off at 11:09 local time and almost six minutes later failed during the second stage of the launcher. Data received from the device indicates that the call was not opened cap, ie the cone of the tip of the rocket where the satellite will stay during the ascent through the atmosphere and to be opened in two halves to release the device, with engaged coping, overweight prevented the placement in orbit of Glory, according to preliminary reports from NASA yet to fully explore all the information for a definitive diagnosis of the fault. It is assumed that the satellite fell into the Pacific Ocean, but has not yet been able to determine the exact location. "We missed the launch into orbit, it appears that the satellite and the rocket ended up somewhere in the Pacific," said launch director Omar Baez.
Scar located on Mars
The Mars Express Orbiter photographed in high resolution scar 78 miles long and up to 25 kilometers wide, located south of Crater Huygens on Mars, and produced by the impact of a meteor shower.
The pictures, published by the European Space Agency (ESA) show in detail the crater have reached as deep as 2000 meters in some places.
The agency said in a statement that the three most profound that can be seen in the photographs are evidence of a possible straight drop of several rocky projectiles.
In addition, the two depressions in the crater with elongated "reinforce the idea of a rain of bullets," he said ESA satellite which photographed the area of Mars on 4 August.
North of that scar is the famous crater called Huygens, of 456 kilometers long, named after the Dutch physicist and astronomer Christiaan Huygens, who discovered Saturn's moon Titan.
