A new study suggests that the Earth could lose up to 60 percent of its atmosphere Collision Space objects that hit the moon
Most scientists believe that this phenomenon occurred about 4 billion years ago when the earth was still evolving. They think that massive matter, probably the size of the planet Mars, is sending to Earth. Steam Particles in space. Gravity is believed to have brought these particles together to form the moon.
Studies provide evidence that this collision could cause up to 10 to 60 percent of the Earth’s atmosphere to be lost. A report on this study was published in the publication Astrophysical Journal Letters.
Researchers’ Effect Hypothesis This is one of the three leading principles of how the moon is formed. Others suggest that the moon was either formed just like the earth, or that it was captured while traveling through space through the earth’s gravitational field.
The researchers decided to explore how heavy collisions of objects affect rocky planets with thin atmospheres. To do this, they operated more than 300 “supercomputers” Similarities”
The experiment takes into account the effect of objects affecting the planet, the speed of impact, as well as the size and mass of the colliding object.
Previous research suggests that impact collisions during the latter Phases The formation of a planet can affect its atmosphere. The computer models of this study have expanded on this idea. They showed that collisions such as the formation of the moon are likely to take up a large part of the Earth’s atmosphere.
The study’s lead researcher, Jacob Kegeris, is with the University of Durham in Britain. He is a cosmologist – a scientist specializing in the beginning and evolution of the universe.
Kegeris noted in a statement that computer simulations do not directly explain how the moon was formed. However, “the effects on the Earth’s atmosphere can be used to mitigate the various ways it is formed.”
The study shows a new way of looking at how similar collisions have damaged the atmosphere of other rocky planets, Kegrais said. Such methods can be used by scientists to investigate how the moon came to be, as well as other very large effects.
The study also suggests that the effects of slow collisions between new collisions and larger objects may increase the Earth’s atmosphere if the colliding object has its own atmosphere.
The researchers say they hope the study will give scientists a better understanding of the moon’s composition and help explain how the atmosphere on other planets evolves.
