?Why does the Nile water run crimson red in the latest satellite images
This bizarre photo of the Nile River makes it look like it's running blood, and you'll never guess why.
Yes, the Nile River is home to one of the fiercest and most aggressive types of crocodiles, which are six meters long and weigh about eight hundred kilograms. These crocodiles have deservedly earned the title of man-eater. They kill more than two hundred people every year, and then there are the Nile river hippos. It weighs 3,600 kilograms, and is also as dangerous as crocodiles, noting that we also did not mention the snakes that this large river is infested with.
All of these ferocious predators mentioned above make you think that the Nile River has many, many reasons for its waters to flow blood, but do not worry, dear reader, there is no reason from the above mentioned that makes the river run in the color that satellite images show, at least this has not happened yet. .
?So why does this image taken by the European Space Agency show the Nile River as if it is flowing with very red blood
High quality image
The long answer, which NASA published on its website, is a very complex answer, but the short and simple answer is that satellites, such as the new Sentinel-3A satellite that took this image, measure many types of electromagnetic radiation below narrow waves. Which falls within visible light, which the human eye can see.
One type of this radiation is infrared radiation. Apparently, the chlorophyll element in plants makes it reflect infrared energy very strongly, and when this is imaged in a satellite image, it turns into the bright, visible red color you see in the image. above.
In other words, the reason why the Nile River has a bright red color in the picture above is because of all the plants that grow on it and around it. The faster the growth of those plants, the darker the red color expressed, and from this, we can be certain that the vegetation around the Nile region He's doing well.
The Sentinel-3A satellite continues its journey around the world, where it will continue to provide necessary data, not only for that related to the growth of plants, but also the entire package of the dynamics that occur around the planet, including monitoring the spread and movement of wildfires, water levels, and much more. of data.
Regarding water levels, and given the recent reports of rising sea levels, we should all be concerned, even terrified, about what the Sentinel-3A satellite might find in the near future.
