sinharapan.co – FOR nearly 12 years, NASA’s Curiosity rover has been actively amassing samples from the floor of Mars and continues to make groundbreaking discoveries.
Latest findings relating to the character of natural matter on the Crimson Planet have challenged scientists’ data of Mars and Earth.
The fabric discovered has traits which might be usually indicative of the presence of microorganisms on Earth.

Nonetheless, this can be brought on by non-biological chemical actions. This discovery, printed in Nature Geoscience, has researchers confused as to the place it got here from.
Based on researchers from the College of Copenhagen and the Tokyo Institute of Know-how, who collaborated on the analysis, this discovery may assist to know how life appeared billions of years in the past on our planet Earth. .
Research co-author Matthew Johnson from the College of Copenhagen referred to as the invention a “smoking gun,” confirming a ten-year-old principle about so-called photolysis within the Martian environment.

“Such complicated carbon-based molecules are important for all times, you can say they’re the foundations of life,” he mentioned.
“So, it is just like the previous debate about which got here first, the hen or the egg. We present that the natural supplies discovered on Mars had been fashioned via photochemical reactions within the environment – with out life. That is the ‘egg’, the prerequisite for all times. Whether or not or not this natural materials helps life on the crimson planet stays to be decided.”
The idea that photolysis, a course of during which molecules are damaged down by mild, performs a job in Martian natural chemistry has been round for a very long time. Nonetheless, sturdy proof to assist this principle has not been discovered.

“What’s fascinating right here is that the carbon isotope ratios in them precisely match our predictions in quantum chemistry simulations, however there is a lacking piece within the puzzle. “We had been lacking one other product from this chemical course of to check that principle, and that is what we now have now,” Johnson mentioned.
These discoveries made by the Curiosity rover in Gale Crater included the depletion of carbon-13 in carbonate mineral samples, which signifies the identical factor present in earlier discoveries of Martian meteorites on was the primary principle established.
This sturdy proof provides us clues concerning the origin of natural matter on Earth.
