The crumbling rock mass found in English fields is a rare meteorite from the early days. Solar systemIt dates back about 4.6 billion years.
The meteorite was discovered in Gloucestershire in March by Derek Robson, who lives in Loughborough, England, and the Director of Astrochemistry at the East Anglia Institute for Astrophysics (EAARO). According to Loughborough University, the meteorite was sitting on a horseshoe-shaped trace left in the field.
Space rock is a carbonaceous chondrite, a rare category that accounts for only 4% to 5%. meteorite It is on earth. These meteorites hailed from the asteroid belt between Mars and Jupiter and were formed early in the history of the solar system. Interestingly, they often contain organic or carbon-containing compounds that contain the amino acids that make up the basic components of life. This raises the question of whether these meteorites have clues as to how organisms first appeared in the solar system.
Unlike other space debris, this block of rock was unable to withstand the violent collisions and heat associated with the creation of planets and satellites in the solar system.
Rather, the meteorite “was sitting untouched past Mars before the planet was created,” said Sean Fowler, a microscopist at Loughborough University. Said in a statement, “It means that we rarely have the opportunity to look into some of our primitive past.”
The rocks are small, charcoal-colored, fragile, and resemble a crumbling concrete block. According to Fowler, meteorites are mainly made up of minerals such as olivine and phyllosilicate, and round particles called chondrules, which were partially molten beads when the asteroid was first formed.
“But its composition is different from that found on Earth and may differ from the other meteorites we have found. Probably an unknown previously found in other recorded meteorite samples. May contain chemistry or physical structure. “
Researchers at Loughborough University and EAARO are using electron microscopy to study the surface of meteorites to nanometers (one billionth of a meter), as well as techniques called vibration spectroscopy and X-ray diffraction. I am investigating chemical substances in detail. Mineral structure in meteorites. If the team can confirm the presence of amino acids in the sample, the findings may reveal new information about how early geochemistry in the solar system set the stage for life. Meteorite research is still in its infancy.
“At this stage, we learned a lot about it, but it didn’t hurt the surface very much,” Loughborough University chemist Sandy Dan said in a statement.
