The atmosphere on Titan is similar to the atmosphere on Earth

Earth's atmosphere was once full of hydrocarbons, mostly methane, instead of nitrogen and oxygen. According to scientists from the English University in Newcastle, the Earth could look to a hypothetical outside observer exactly the way Titan looks today, i.e. hazy pale yellow.

This began to change about 2,4 billion years ago as a result of photosynthesis in microorganisms that develop on Earth. It was then that the accumulation of the product of photosynthesis, oxygen, began in our atmosphere. British scientists even describe the events that took place there as a "great oxygenation". This went on for about 150 million years, after which the methane fog disappeared and the Earth began to look like we know it now.

Scientists describe these events based on analyzes of marine sediments off the coast of South Africa. However, they cannot explain why it started then. intensive saturation of the Earth with oxygenalthough photosynthetic microbes were present on our planet many hundreds of millions of years ago.
