The process began with cyanobacteria. The fungi were Penicillium decumbens, Cladosporium cladosporioides , Alternaria sp. Some bacteria, lichens Xanthoria elegans , Rhizocarpon geographicum and their mycobiont cultures, the black Antarctic microfungi Cryomyces minteri and Cryomyces antarcticus , spores, and even one animal tardigrades were found to have survived the harsh outer space environment and cosmic radiation. Griffin speculates that viruses evolved in comets and on other planets and moons may be pathogenic to humans, so he proposed to also look for viruses on moons and planets of the Solar System. The purple membranes, amino acids and urea were not measurably affected by the dehydrating condition of open space, if sheltered from solar radiation.

Thermosphere - Starts at 80 or 85 kilometres 50 or 53 miles. Pyrimidine, like polycyclic aromatic hydrocarbons PAHs , the most carbon-rich chemical found in the Universe , may have been formed in red giants or in interstellar dust and gas clouds, according to the scientists. These structures may be highly resilient to ultraviolet and gamma radiation , desiccation , lysozyme , temperature , starvation and chemical disinfectants , while metabolically inactive. For the flu pandemic they hypothesized that cometary dust brought the virus to Earth simultaneously at multiple locations—a view almost universally dismissed by experts on this pandemic. These calculations show that relatively near target stars Alpha PsA, Beta Pictoris can be seeded by milligrams of launched microbes; while seeding the Rho Ophiochus star-forming cloud requires hundreds of kilograms of dispersed capsules. It is now known that extremophiles , microorganisms with extraordinary capability to thrive in the harshest environments on Earth, can specialize to thrive in the deep-sea, [] [] [] ice, boiling water, acid, the water core of nuclear reactors, salt crystals, toxic waste and in a range of other extreme habitats that were previously thought to be inhospitable for life. This positively charged molecule then draws in a nearby reactant by electrostatic attraction of the neutral molecule's electrons. The process began with cyanobacteria. Their methods failed to recognize a well-known functional association in the genetic code; they did not rule out the operation of natural law before rushing to falsely infer design The chemicals, found in a giant cloud of gas about 25, light-years from Earth in ISM, may be a precursor to a key component of DNA and the other may have a role in the formation of an important amino acid. The first suggestion came from Chandra Wickramasinghe , who proposed a polymeric composition based on the molecule formaldehyde CH2O. There is little water vapor and other substances in this layer. Biologically relevant molecules identified so far include uracil , an RNA nucleobase , and xanthine. The Lancet subsequently published three responses to this letter, showing that the hypothesis was not evidence-based, and casting doubts on the quality of the experiments referenced by Wickramasinghe in his letter. Despite great initial excitement, the seed was found to be that of a European Juncaceae or Rush plant that had been glued into the fragment and camouflaged using coal dust. It is generally agreed that the conditions required for the evolution of intelligent life as we know it are probably exceedingly rare in the universe, while simultaneously noting that simple single-celled microorganisms may be more likely. The data support the likelihood of interplanetary transfer of microorganisms within meteorites, the so-called lithopanspermia hypothesis. After the approximately month mission, their responses were studied in terms of survival, mutagenesis in the his B. Ends at 50 kilometres 31 miles. Out of the 12 bacterial samples, three were identified as new species and named Janibacter hoylei after Fred Hoyle , Bacillus isronensis named after ISRO and Bacillus aryabhattai named after the ancient Indian mathematician, Aryabhata. Griffin speculates that viruses evolved in comets and on other planets and moons may be pathogenic to humans, so he proposed to also look for viruses on moons and planets of the Solar System. Of the 6 missions flown so far on BIOPAN between and , dozens of experiments were conducted, and some analyzed the likelihood of panspermia. They were the first organisms to make free oxygen by photosynthesis. However, in November , a team of scientists at Johnson Space Center , including David McKay, reasserted that there was "strong evidence that life may have existed on ancient Mars", after having reexamined the meteorite and finding magnetite crystals. Nothing in the genetic code requires design.

Most organisms today need oxygen for their respiration ; only a few anaerobic organism s can grow without oxygen.

    Molecules can also be generated by reactions between neutral atoms and molecules, although this process is generally slower. Thermosphere - Starts at 80 or 85 kilometres 50 or 53 miles.
