Red rain which caused fear and panic in four different areas in the country namely, Monaragala, Polonnaruwa, Sewanagala and Manampitiya leaving red frost in the latter two districts, continue to baffle local scientists still studying samples of the freak showers.
Similar showers of ‘blood rain’ were experienced in Kerala, South India during two consecutive months from July to September this year, spawning several scientific and non-scientific theories with regarding to its origin.
So from where exactly does this mysterious rain originate? Is it from the earth whose natural elements we are familiar with having growing in these environments since the day we were born? Or from some extraterrestrial origins we are completely alien to? Scientists studying samples of the red water at the Medical Research Institute and other institutes such as the Industrial Technological Institute (ITI) and universities told The Nation that they have yet to come to a definite conclusion, although not ruling out algae as a possible cause. While Health Ministry officials claim that the microorganisms contained in the ‘red rain’ is Trachelomonas, Medical Research Institute (MRI) Microbiologist Dr Sujatha Pathirage said that the microorganisms are usually found in contaminated water.
The Nation beliefs that the red rain may be extraterrestrial in origin. However past instances of “red rain” have been attributed to particles of sand or airborne spores from locally prolific terrestrial algae.
