Red Rain is a phenomenon that seems to be rare and has strange properties. Many papers have been written and this one in 2001 by Rajkumar Gangappa, Chandra Wickramasinghe, Milton Wainwright, A. Santhosh Kumar and Godfrey Louis theorize that Red Rain cells when nurtured and incubated actually start to grow.
This is interesting since they also theorize that Red Rain has an interstellar origin:
Following incubation at 121oC for 1 hour and longer, a marked change occurs in the internal appearance of the Red Rain cells (Fig.4 c (i) and d (i)), as small cells appear in the original larger cells. These small cells can be regarded as “daughter cells” having the same morphology as their “mother cells”. The size of the daughter cells ,after 1h exposure to 121oC, ranges from 30 nm to 120 nm in size (Fig 4 c (i), (ii) and b (i), (ii)). The cell wall of these daughter cells is seen to thicken following incubation for 2hours (Fig.5 (i) and (ii)).In conclusion, the results of the present study clearly establishes that red cells discovered in the Kerala rain, replicate at 121oC and that there is a significant increase in the number of cells after incubation at 121oC. Furthermore, optical microscopy and electron microscopy of post-incubated red cells confirms that these cells are hyperthermophiles. The formation of daughter cells having the same morphology as the mother cells clearly shows that Red Rain Cells are not single endospores, such as those seen in bacteria, such as species of Bacillus and Clostridium.The optimum growth conditions and upper temperature limit of these cells is yet to be determined. Although autoclaving at 121oC for 20 mins kills most microorganims, some spores of Bacillus and Clsotridium species can resist this treatment and germinate to form vegetative cells when incubated at lower temperatures (Hyum et al,1983,Vessoni,et al.1996). Here, however, we have shown that, unlike heat resistant bacterial spores, Red Rain cells grow and produce daughter calls when incubated at 121oC for 2 hours. The results of these experiments show the remarkable ability of Red Rain cells to grow and replicate at 121oC and thereby supports the hyperthermostability of red cells, as reported by Louis and Kumar (2003); no attempt however, was made to confirm their claims that Red Rain cells grow at 300oC.The origin of Red Rain, and the cells that it contains, has yet to be discovered, although the results of this study suggest that, since such cells are adapted to growth and reproduction at high temperatures, they likely originate in an extreme environment which is at times exposed to high temperatures; whether such environments occur on Earth, or elsewhere, has yet to be determined. (Emphasis mine).[...]While the origin of the red rain cells remains uncertain, the possibility of their astronomical relevance has been suggested in several papers (Louis and Kumar, 2003, 2006). In this connection, the hyperthermophile properties discussed in the present paper and the unusual fluorescence behaviour are worthy of note.We conclude this section by comparing spectra in Fig 7 with astronomical spectra of a fluorescnence phenomenon (ERE emission) for which no convincing abiotic model is still available, Fig 9 shows normalised ERE emission in several astronomical objects and Fig 10 shows the same emission in the famous Red Rectangle, a nebulosity associated with a planetary nebula (Witt and Boronson, 1990; Furton and Witt, 1992, Perrin et al, 1995, Hoyle and Wickramsinghe, 1996). Although non-biological PAH explanations are still being attempted their success has so far been minimal.[...]A spectrum of starlight from a blue star could provide the range of excitaton wavelengths that corresponds to those involved in Fig. . The correspondence of profile and peak fluorescence wavelength between the red rain spectra and the ERE spectrum of the red rectangle is impressive. We conclude this paper with a recollection of an earlier comment published by Hoyle and Wickramasinghe:“Once again the Universe gives the appearance of being biologically constructed, and on this occasion on a truly vast scale. Once again those who consider such thoughts to be too outlandish to be taken seriously will continue to do so. While we ourselves shall continue to take the view that those who believe they can match the complexities of the Universe by simple experiments in their laboratories will continue to be disappointed.” (Emphasis mine).
Very interesting indeed. Red cells from interstellar space that resemble red blood cells ?
Do we live in a biological Universe where Panspermia runs wild?
Or are we reading the signs wrong?
