(RNN) - In an image shared from space on Friday, the Nile River appeared to be blood-red, reminiscent of a Biblical tale and the Plagues of Egypt. 

However, the river wasn't actually turned to blood. The image, released by the European Space Agency, was created by the satellite Sentinel-3A, which uses a radiometer to measure visible and infrared energy. In short, the red hue of the river represents vegetation, not an allegory from the Bible. 

The agency uses the satellite to monitor land use, wildfires, bodies of water and the aforementioned plant life. 

In the Biblical story, Moses turned the Nile River to blood by dipping his staff in ancient body of water.
