Researchers keep looking for evidence of alien life on Mars, and they have been doing it for decades. They are doing several challenges, and they are taking a lot of risks. But there’s a new study there which shows that the search for life on Mars could get easier by solving fossil mystery.
A recent report suggested that the findings of the research conducted by a team from the University of Edinburgh clarify the probes on Mars that they should go after.
As per the study, the microscopic tubes and the filaments are referred to as being the skeletons of a tiny creature, but they might be residue which formed after chemical reactions with iron minerals. Previous research showed that the remains are the oldest fossils on Earth.
Is life on Mars real?
The leading research of the study, Sean McMohan, has studied structures that were alike in the lab. It can help researchers to avoid analyzing unnecessary data. He wants to find the answer to a burning question: does life exist on Mars? Has it ever existed?
For the study, he created tiny fossils in the lab, which are an accurate replica of the structures rich in iron, which are found in Mars-like rocks on Earth. They believe that some of the remains are about 4 billion years old. So they are considered to be a massive help in the study of life.
With the help of a mix between the iron-rich particles and alkaline liquids with chemical silicate or carbonate, the structures were created. The process was known as chemical gardening, and it is actually a natural phenomenon. Some of these structures are found on hydrothermal vents or in fissures in the seafloor. They are very intriguing for explorers. But McMohan suggested that the structures may not be a good proof for the fossils.
