New Review of Famous Martian Meteorite Finds No Evidence of Extraordinary Life

The material buried under the Allan Hills 84001 meteorite — a piece of rock formed on Mars 4 billion years ago — is made up of water other than the Martians, according to a new study. But scientists who believe in the fossil record are uncertain.

The 4 billion-year-old fragment of Mars formed during the Great Depression of Noah, was thrown into space by a giant giant 17 million years ago, and landed on Earth 13,000 years ago. Named Antarctic Allan Hills, the meteorite weighing 4.3 pounds (1.94 kg) is one of the oldest extant finds.

A team of scientists under NASA surprised the world in 1996 with courage give ideas that the larvae of carbonate globules on the meteorite were buried in the ground, hence the first evidence of a strange life. Many scientists are skeptical of this interpretation, citing other “biomorphs,” such as volcanic eruptions, events, and exposure to water. Most scientists agree that there is no evidence of life on ALH84001, but this controversy continues after more than a quarter of years.

A recent headline on this issue appeared on Thursday – a new one paper in Science that also makes abiotic processes have a role in meteorite visibility. The new paper explicitly states that the natural molecules found in meteorites are formed from slow and stable movements due to groundwater filtering broken rocks. Astronomer Andrew Steele from Carnegie Institution for Science led a new study.

Now, just because something is described as “organic” does not mean it has anything to do with life. Natural molecules are composed of carbon and hydrogen, and sometimes oxygen, nitrogen, and sulfur. Of course, these molecules are often linked to living things, but they are also derived from natural materials, known as abiotic organic chemistry.

According to this new study, “Mars’ crust has discovered complex molecules in the earth’s crust exposed by methane in the modern atmosphere,” the new newspaper reminds us. “It is unknown at this time what he did to create the organic matter, and it is speculative to combine biotic and abiotic sources.” It was through an analysis of salt extracted from ALH84001 that the team made an effort to understand “the historical processes of Earth’s history and the potential for Mars to survive,” Steele, a member of NASA’s scientific team Perseverance and Curiosity, explained in Carnegie Press release.

Indeed, this new study is further attempted to refute the claim that ALH84001 contains Martian residues. The study also explores the background of Mars and the Earth, how these elements can form the basis of life, and why Mars reflects the conditions we see today, such as the presence of methane. “Mars’ biological research is not just about answering the question ‘are we alone?’” Says Steele. “It has to do with the original nature of the Earth and it answers the question, ‘Where did we come from?’”

Steele and colleagues used nanoscale microscopic imaging, spectroscopy, and isotopic meteorite analysis, which led them to claim that natural molecules are formed as a result of interactions between liquids, either salts or salts, and basalt rocks.

The paper states that one of the two possible geochemical factors led to the integration of organic compounds: serpentinization and carbonization. In serpentinization, hot stones containing iron or magnesium interact with surrounding water, resulting in the formation of hydrogen, and in carbonization, acidic water containing soluble carbon dioxide bonds with rocks, resulting in carbonates.

Scientists say it is not clear which of the two is responsible for the actual events, but it does say that it happened over a long period of time, that it was made from carbon dioxide emissions, and that it was abiotic. the process itself was responsible for the carbon-rich groups.

Scientists who conducted the 1996 study were not pleased with the new paper, such as The Guardian. reports. They say that does not provide new information and no translation is supported by the evidence, adding “[u]Supported myths do not solve any problem that surrounds the origin of living things ”in a meteorite.

So the argument continues. Koma tone rock cannot answer the question of whether life existed, or still exists, on Mars. In this case, the best way we can do this is through a return visit, which is a good start. NASA’s Perseverance rover is currently collecting and setting up surface samples for future reference. on Earth, probably in the early 2030s.
