An ancient cosmic storm could shape ourSolar system. This unexpected conclusion was made by specialists from the Southwest Research Institute in Colorado. Some time after the planets found their true form, a series of resonant shocks between giant planets knocked them out of their usual orbits, causing them to “roam” the system for a while. According to sciencemag.org, scars on the moon convinced most planetologists that a cosmic storm occurred about 3.96 billion years ago, 650 million years ago after the formation of the solar system. However, such a theory does not fit into the framework of the familiar picture of planetary processes that took place at the dawn of the formation of our stellar system. Perhaps everything that we know about the solar system is wrong?
Space storm rearranged the planets of the solar system
Two decades ago, scientists recognized that inthe distant past of the solar system, planets had to migrate from their usual places in order to create our unique planetary system in the form in which we know it now. According to the model presented by planetologists from the University of the Cote d'Azur, after giant planets formed from a gas disk, Jupiter pulled its giant brothers into a resonant chain of orbits, where Saturn rotated around the Sun three times in two turns of Jupiter. The gas surrounding the planets acted as a shock absorber, calming any instability, but as soon as it dissipated, the attraction of the masses of giant planets unleashed real chaos.

Analysis of lunar rocks collected from percussionof craters by Apollo astronauts, revealed that the moon suffered a major cosmic cataclysm about 3.95 billion years ago. The large-scale event was called the Late Heavy Bombing and suggests that the stones collected by astronauts in several craters are fragments of a powerful blow that created the Imbrium basin. A more accurate dating of lunar meteorites shows that the collisions occurred 4.3 billion years ago - much later than previously thought.
In a new article published in Icarus magazine,researchers prove how an earlier cataclysm could explain some of the strange features of the solar system. So, early instability could explain the presence of an asteroid belt between Jupiter and Mars, destroying planet-forming material on the border of the outer and inner parts of the solar system. In addition, the compact shape of the belt could appear due to the last stage of the instability of the solar system, during which the last jerk of Saturn from Jupiter threw the residual material after the formation of the planets into the current orbit.

Although there is direct evidence of earlyThere is almost no instability of the solar system, scientists intend to analyze the noble gases measured by the Rosetta spacecraft near comet 67P. According to the calculations of experts, instability could cause a bombardment of the Earth by a hail of comets almost immediately after it became solid. In addition, the icy composition of the double asteroid Patroclus-Menoetius, rotating in the orbit of Jupiter, may indicate that the object was originally formed in the remote corners of the solar system and was subsequently pulled by a giant planet into its vicinity.
Be that as it may, there is a high probabilitythat the ancient cosmic storm contributed to the development of life on Earth. So, giant planets, located in their modern orbits, perfectly protect the Earth from the invasion of asteroids and comets from the borders of the solar system, and the ancient comet city could well become a source of water so necessary for organic life.
