The bomber struck shortly after noon in front of a crowd of about 1,200, injuring at least 30 people.

A team of astronomers at the University of Cambridge (United Kingdom) and the Chinese Academy of Sciences have reconstructed the history of a 2013 meteorite that fell in the vicinity of the Russian city of Chelyabinsk. It may have originated as part of a massive collision between the Earth and the Moon during the formation of our solar system.

One of the most widely accepted theories is that planets are the result of collisions between giant asteroids and protoplanets. These events leave a mark on the minerals that make up the celestial bodies, and although they are not always easy to find on Earth’s surface due to the constant renewal of strata, they are best preserved in meteorites. To explain Researchers.

As described by academic experts in an article Published This Thursday in the journal Communications Earth & Environment, they linked the results of the meteorite’s radiometric dating with the microscopic analysis of the minerals it created, to determine the number of collisions it encountered before crashing into the Urals. And how to adjust them over time

According to the authors, the practical methodology allowed them to identify at least two major impacts. The first of these, considered the largest, occurred a few years ago. 4.5 billion For years, as a result of the collision of two large planets, the Earth-Moon system is believed to have formed a transition corresponding to the moment it is believed to have formed.

They also found evidence of a recent second match 50 million Years old, it is suspected to have caused a fragment to split from a host asteroid and crash into Earth. Impact of the Urals on the Russian region a Explosion It is equivalent to the explosion of 30 atomic bombs in Hiroshima, injuring more than 1,200 people.

The results, experts explain, support the findings of other investigations that suggested multiple high-energy collisions between celestial bodies a few years ago. 4.480 to 4.440 million Of years. “The fact that all of these asteroids are undergoing intense melting at this time may indicate the reorganization of the solar system as a result of the formation of the Earth and the Moon or as a result of the orbital motions of the giant planets,” Craig said. Walton, co-author of the publication.

Novel study provides valuable information to understand the process that led to our cosmic neighborhood, astronomers point out. As such, they guarantee that their explorations will continue, and hope that there will be a reduction in the window of lunar formation that can provide new evidence of how our own planet came to be.
