Scientists have found traces of fatty acids – key building blocks of biological cells – in acid waters in the UK, indicating that once upon a time there was life on Mars.
"Mars swallowed water billions of years ago, which means that some form of life could thrive there," said Mark Sephton, head of the Imperial Department of Earth Sciences.
"If life existed before the water dried up, it would probably have left remains preserved to this day in Marsstein," Sephton said.
Dorset, in the UK, is home to highly acidic sulfur streams that harbor bacteria that thrive in extreme conditions.
In the Bay of St. Oswald, conditions on Mars are mimicked billions of years ago, researchers say.
They treated the landscape as a template for Mars and examined the organic material in nearby rock deposits.
The iron-rich mineral goethite transforms into hematite, which is very common on Mars and gives the planet its red color.
If these iron-rich minerals contain traces of life on Earth, they may contain clues to microbial life on the red planet.
The Study, Pub Scientific Reports reported that Goethit in St. Oswald's Bay harbored many microbes and traces of their fossilized organic remains.
The researchers used these results in a Martian environment.
Based on how much rock it comes from Assuming that the concentration of fatty acids in Mars sediments matches that of the Earth, there could be as many as 2.861
Previous Missions To find traces of life, they investigated rocks for organic matter.
Scientists suggest that heat reacted minerals with organic matter, which explains why we have not found any traces of life.
The heating of goethite or hematite, however, does not destroy organic matter, which means that these minerals could be good targets for life.
"We have not found any convincing traces of orga nic matter that would indicate previous life on the red planet," said Septhon.
