Red rain in India has an extraterrestrial life form

Extraterrestrial life form may have already lives on Earth - the people. There is a common, but not popular, the idea of the scientific community, according to which life on Earth has been brought comet, asteroid or meteor that contained the building blocks needed for the start of the evolutionary process.

This theory is called "panspermia" and she has been the subject of scientific debate 15 years ago when some scientists have argued that Martian meteorite found in Antarctica contained traces of life.

Scientists have shown that some forms of life can survive being in outer space. Also it was proved that the temperature inside Mars meteorite during its flight to the earth did not rise above 50 degrees Celsius.

Unfortunately for seekers of extraterrestrial life, these cells can also be found on the Earth, so the dispute has remained unfinished.

In July 2001, India went red rain. And not just red, the newspaper The Hindu claimed that within a few months after the red rain, eyewitnesses reported a yellow, green and black rain.

First, there was the theory of the impurities of sand or dust from the desert. However, a local physicist, Godfrey Louis, found under a microscope, the water contained cells that looked like a virus.

Five years later, he published the theory that the virus, which is painted in red rain could come to Earth with a comet that exploded above the Earth, and disappeared into the clouds.

Today, after four years of study of cells, together with the leading panspermia theorist from the UK Chandra Wickramasinghe, Professor Louis issued a statement in which he expressed doubt as to their terrestrial origin.

According to him, these cells are inactive at room temperature, but begin to multiply at a temperature of 121 degrees Celsius.

Within two hours of the temperature regime, "daughter cells arose from the original mother cells and the number of cells increased with increasing time during which they were subjected to thermal effects" - they said in their report.

Although many spores on Earth can survive in such extreme temperatures, but they can not grow under these conditions, and especially do not require such temperatures for the beginning of the process of reproduction.

The team also discovered that the cells changed their unusual coloring under UV irradiation, which is known as the "fluorescent behavior."

They reported that it was "remarkably consistent" red light of the planetary nebula Red Rectangle, which is located at a distance of 2,300 light-years away from us, "gives reason to suppose that, although no proof of extraterrestrial origin."

Although the theory of panspermia has been rejected by the scientific community for the most part, but the final report of the team of Professor Luis caused great excitement - because cells do not contain DNA.

"As a biologist, I find that organisms resembling the shape and size of a cell that can live outside the culture medium and the lack of DNA and RNA on their own - a revolutionary discovery" - wrote one commentator in the journal TechnologyReview.

Only life form on earth, which dispenses with the DNA according to another commentary - are proteins known as "prions" that cause BSE. Discovery of the team, have not yet been verified. Popular news informers tell about the most important events of the day.
