Scientists Unraveled Mystery of Spanish Bloody Rain


Chemists at the University of Salamanca (Spain) found that the "apocalyptic" rainfall in the west of the country were caused by red algae, trapped in the upper atmosphere.

Scientists unraveled the mystery of Spanish bloody rain

Water of the blood-red color was found in the village of Zamora last fall, just after the rain. It was everywhere - in the basins, barrels and even rivers. Local residents were scared, and one of them has collected samples of water and gave them to the lab. As it turned out, the cause is freshwater algae Haematococcus pluvialis, which contain astaxanthin, a substance used in industry as a colorant, and an antioxidant. Experts suggest that these microbes got to Spain from North America, and they got into the rain clouds as the result of the tornado. Similar phenomena have been observed on the planet since ancient times, and there is nothing supernatural.
