Pale Green Dot Study Claims Earth Oceans was not all Always Blue they were green instead

Earth is also called blue planet. The reason is its blue ocean that shows it like a blue ball from space. But was the Earth always surrounded by blue seas? The new study says something else. The host Carl Sagan of the show once described Earth as Pale Blue Dot in the Popular TV show Cosmos. Actually Carl was telling about a photo of the earth taken by Voyager 1. It is said that the Earth was not blue at a time. It was seen in some other color.

Humans have so far seen the earth in blue. The new study says that there was a time in the past when the Earth’s oceans shone in green color! Nature This study published in the journal (via) Has been done. In which it is reported that about 2.4 billion years ago, the Earth’s ocean was seen bathing in green in Archaean Era. Prior to the flourishing of life on Earth, the hydrothrimal vent, which bursts in the foothills of the oceans, pumped up the water in the water (the iron accumulated in the absence of oxygen), filled with the sea iron (ferrous iron).

Since there was no presence of oxygen in the atmosphere at that time, Sagar could not even reflect in the sky. After the arrival of cyanobacteria, oxygen started to be made in water. This oxygen converted the ferrous iron into ferric iron that created particles such as war.

Ferric iron was lying in water as hydroxide. Due to its non-soluble nature, it created an optical effect that absorbed red and blue wavelength. But it allowed the green light to pass through this effect. For this reason, the ocean started appearing in green. Had there been a camera at that time, the Emerald would have been seen in the Emerald Green color.

Scientists have also proved this theory. Researchers thought of using a green colored pigment called phycoreithroobilin. For this, he generated modern cyanobacteria genetically. These modified microorganisms developed better in green lights, which was somewhat duplicated the natural phenomenon that had occurred billions of years ago.
