Scientists claim ancient life on Mars is the explanation for the latest discovery of rovers

Ancient life on Mars is one of the possible explanations for the recent discovery of Nasa’s Curiosity rover.

The rover is currently roaming the Red Planet, collecting samples and trying to determine if there was ever life on Mars.

New analysis of one of the submersible sediment samples shows the presence of carbon.

Carbon is the basis of all life on Earth, so scientists are excited about its presence in a sample of Mars.

It’s not a sure sign of life, but carbon atoms help track biological activity on our planet.

That means they could help researchers determine if there was ever a life on Mars.

Carbon atoms could provide insight into the planet’s ancient carbon cycle.

New carbon discoveries were recently published in the journal Proceedings of the National Academy of Sciences.

Nasa’s Curiosity rover collected sediment samples from the 96-mile-wide Gale Crater on Mars from August 2012 to July 2021.

It is thought that this crater was once inhabited by an ancient lake.

The crater provides 24 samples which are then heated to separate them into particles.

Curiosity then measured the elements inside and found that some samples were rich in carbon and some were depleted of the element.

“Extremely depleted carbon 13 samples like those in Australia were obtained from 2.7 billion-year-old sediments,” said Christopher H. House, lead author of the study.

“Those samples are caused by biological activity when methane was consumed by ancient microbial mats, but we don’t necessarily say that on Mars because that’s a potentially habitable planet.” formed from materials and processes other than those of Earth.”

Microorganisms develop into large colonies known as carpets on Earth and deplete carbon and other materials from their existence.

If Gale Crater is home to a lake, it could be home to similar bacteria.

This is something the researchers have not ruled out.

Other theories as to why Mars has carbon in its sediments include a cloud of galactic dust or ultraviolet-induced decomposition of carbon dioxide.

The researchers plan to take and study more samples from Gale Crater.
